Giant Rex
Level 4
Dinosaur/Effect/EARTH
2000 ATK/1200 DEF
Cannot attack directly. If this card is banished: You can Special Summon this card, and if you do, this card gains 200 ATK for each of your banished Dinosaur monsters. You can only use this effect of "Giant Rex" once per turn.
The negative effect might turn off players from using it, but it's actually really damn good. Mix in Evilswarm Salamandra and you basically have a Dino that keeps on coming back thanks to Salamandra's effect of banishing monsters. It also allows plays with Tyranno's other good card "Survival's End" which I'll get to in a bit. Plus, if you're up against say Spellbooks or Amazoness, it can come back after being banished which is great, allows you to have an option to prevent your opponent from attacking directly.
Black Stego
Level 4
Dinosaur/Effect/EARTH
1200 ATK/2000 DEF
If this face-up Attack Position card is targeted for an attack: Change this card to Defense Position.
It's an alright effect, but I feel like that because of how the meta has evolved so far in DL, it's not that very useful. Since Enemy Controller exists, Super Rush Headlong and Koa'kis being piles of trash make it something I can't recommend. Maybe if you want a wall.
Miracle Jurassic Egg
Level 4
Dinosaur/Effect/EARTH
0 ATK/2000 DEF
While face-up on the field, this card cannot be banished. Each time a Dinosaur-Type monster(s) is sent to your Graveyard, place 2 counters on this card. You can Tribute this card; Special Summon 1 Dinosaur-Type monster from your Deck whose Level is less than or equal to the number of counters that were on this card.
Honestly, I don't think this is that good of an option for Dinos, since there are much better options for players to run and play. So maybe skip on this one, unless you want another wall.
Volanic Eruption
Normal Trap
During your End Phase, if you control "Jurassic World": Destroy all cards on the field.
This seems far too situational to be an SR. Since you could fear that your opponent can either Banish it, lock it down or even Vision HERO it off too. Not something I'd recommend.
Survival's End
Normal Trap
Destroy as many Normal Monsters on the field as possible, and if you do, Special Summon Level 4 or lower Dinosaur-Type monsters from your Deck, up to the number destroyed, but destroy them during the End Phase. You can banish this card from your Graveyard, then target 1 Dinosaur-Type monster you control and 1 card your opponent controls; destroy them.
Now this... THIS. Is a damn good card! Sure, it requires you to sack Normal Monsters, but this includes YOUR OPPONENT'S too. So Blue-Eyes decks can get snuffed from this which is great. Even Paleozoic cards count as Normal Monsters too, so you could Special Summon it to the field and have it get sacked for Survival's End's effect. Not only that, its secondary effect when in the GY is amazing. Allowing you to get rid of one Dino on the field (Presumably Giant Rex) to destroy any card on your opponent's field. Fantastic card imo. And since it isn't a Once Per Turn effect, you can easily swarm the field and go crazy.
Frostosaurus
Level 6
Dinosaur/WATER
2600 ATK/1700 DEF
This monster's metabolism enables it to endure long periods of cold, harnessing the power to become a creature of solid ice! Nothing else can withstand such temperatures, especially victims of its glacial rampage.
It's a Normal Monster, I wouldn't recommend it.
Black Veloci
Level 4
Dinosaur/Effect/EARTH
1800 ATK/300 DEF
If this card attacks an opponent's monster, this card gains 400 ATK during the Damage Step only. If this card is attacked by an opponent's monster, this card loses 400 ATK during the Damage Step only.
Ehhh... This is basically Steamroid and that one X-Saber Galahad. Wouldn't suggest this at all.
Evoltile Pleuro
Level 1
Dinosaur/Effect/FIRE
200 ATK/200 DEF
If this card you control is destroyed and sent to your Graveyard: You can Special Summon 1 "Evolsaur" monster from your hand.
Since we don't have Xyz yet, I can't say this is good. Don't bother with this card at all.
Evolsaur Terias
Level 6
Dinosaur/Effect/FIRE
2400 ATK/600 DEF
When this card is Special Summoned by the effect of an "Evoltile" monster: This card loses 500 ATK.
Again, no Xyz yet. So don't bother.
Little D
Level 3
Dinosaur/EARTH
1100 ATK/700 DEF
Yo, this tyrannosaurus tot's got a terrible temper.
Oh look, it's Exodia's 6th Piece.
Also, I should mention Ultimate Tyranno's UR exclusive too.
Stegocyber
Level 6
Dinosaur/Effect/DARK
1200 ATK/2400 DEF
During damage calculation, if your opponent's monster attacks while this card is in your Graveyard: You can pay 1000 LP; Special Summon this card, and if you do, you take no battle damage from that battle, but banish this card when it leaves the field (this is a Quick Effect). You can only use this effect of "Stegocyber" once per turn.
It can be decent as a solid wall, but the cost can be a bit much maybe. Sure the damage negation is nice, but you have to remember that Koa'kis are roaming about and can just deny you of this. And even OTK you. So eh. Not the best card out of Tyranno's Rewards, but I'd say it's an okay card.
