Habenero your challenge has been accepted. My moveset will be more combo-oriented so I hope this might convince you at least that Chrom has viability in terms of his moveset. Though my moveset probably isn't the most original/creative out there I thought I'd give it my best shot.
Chrom moveset:
(I'm not aware of any official names so I will make them up along as I go. I will also be referring to this video:
http://www.youtube.com/watch?v=5NpJ_afFukQ . THIS VIDEO HAS SPOILERS AS IT CONTAINS CUTSCENES FROM FIRE EMBLEM AWAKENING)
B: Critical Hit. Like all Fire Emblem characters Chrom has a chargeable B neutral. The charge mechanic would be similar to DK's and Samus' B neutral where you are free to stop charging/recharge at your will. This attack would cause Chrom to leap-strike a certain distance in front of him and strike the foe dealing damage and causing them to fly forward based on how long the attack as charged. Knock-back exponentially increases based on how much damage the target already has. Targets struck while having low % will not fly far back for combo purposes.
The leap can be partially controlled with the control stick. Forward tilt causes Chrom to leap the maximum distance while the backward tilt causes Chrom to leap the minimal distance. Tilting the control stick upwards would cause Chrom to leap higher and likewise, tilting the control stick down while leaping will cause Chrom to perform a smaller and quicker leap. If Chrom strikes an enemy he will backflip off the enemy which provides him distance as well as being able to prepare for a combo on targets with low %. Striking some lightweight and most medium/heavyweight characters at 0-12% with a fully charged Critical Hit will still allow Chrom to connect his B>. (Meaning the distance an opponent flies when struck with a fully charged Critical Hit at around 12% under normal circumstances will be up to the maximum distance of his B>.)
You may also choose to perform aerials while backflipping but you will not be able to combo into B> right away.
B>: Falchion Dash. This is seen between 5:56-6:00 in the clip. This skill will work similarly to Fox and Falco's B> in that it activates quickly and cannot charge. This attack allows for Chrom to gap-close towards a foe and knocks the opponent straight up. (Attacking most enemies between 18-34% will put them within range of Chrom's B^) Unlike Fox and Falco's B> Chrom will stop immediately after hitting a target or travels the maximum distance if no target is hit. If the input for another Special Move (B Neutral, Bv, or B^) is used while in mid charge Chrom can immediately perform that attack, thus prematurely ending his gap-closer. *If Critical Hit is used while Chrom performs Falchion Dash he will perform the leap strike based on how much his Critical Hit was charged.
B^: Falchion Finality. This is seen between 3:43-3:45 in the clip. This will work similarly to Bowser's Bv in that Chrom will leap straight up in the air and plummet towards the ground with the Falchion pointed downwards. Enemies hit by this attack will be sent flying upwards and towards the direction Chrom is facing when he performed the attack. You can cancel this attack as long as Chrom is not performing the second half of the attack when he is plummeting towards the ground. In doing so you can immediately perform his Bv or any aerials.
**Bv: Falchion Dive. This attack is seen between 5:40-5:45 in the clip. Chrom jumps in the air and performs a spinning attack diagonally downwards in the direction he is facing. This attack must be used while Chrom is in the air. If Chrom is standing on the ground he will automatically jump (Using one of your two available jumps) and perform the attack. If Chrom uses this attack while in the air, as long as he has adequate distance between him and the ground beneath him, he will immediately perform the spinning attack without leaping into the air. This attack does not cause large knockback though it does induce a decent amount of hit-stun if the attack connects.
Typical combos on most low % enemies can include:
B Neutral into B> into B^
B Neutral into B> into B^ (Canceling the second half of the attack) into Bv.
B> into B neutral into B>
Bv into B Neutral into B>
***Final Smash: Dual Strike. One of Fire Emblem Awakening's main selling point is the ability to perform a Dual Strike with your teammates. When Chrom activates his Final Smash he will catch opponents in an area in front of him. (Chrom and the enemies he 'catches' will be taken off screen much like Captain Falcon's Final Smash) Luciana (masked or unmasked) will then arrive from the Outrealm and assist Chrom in his Dual Strike. Luciana will perform a barrage of attacks in quick succession depending on the number of enemies caught and will then provide Chrom his Dual Strike bonuses when she has finished. Chrom will then perform an over-glorified, fiery, impressive, awe-astounding, and explosive final attack to each target caught. (And of course he will get a cut-in) When the Final Smash is over all targets will be sent flying upwards and the direction Chrom faced when they were caught.
** The reason why Falchion Dive is not Chrom's B^ is because attempting to get back on the stage will prove to be an absolute nightmare if the foe is even semi-decent at edge-guarding. In terms of a recovery it is much too easy to counter as it requires Chrom to be above the stage.
*** I decided that unless we get two Awakening characters Luciana is extremely unlikely so therefore she will have her cameo here.
Please feel free to bash/provide constructive criticisms as you see fit.
