Wario vs Link:
It could be -1 or -2 for Link. The main reason MUs are that bad for Link is the gimping factor. If Link makes any errors offstage he's down a stock and Wario has good tools to gimp him with. Otherwise -1. Link can be crafty and recover; it's not "Link offstage means he's free" like some people think but he is in a very bad position.
Link's pros
*Link walls off Wario decently with projectiles and good reach.
*All around better disjointed reach with attacks.
*Link builds free damage by playing keep away when he can.
*Zair and Bombs cannot be eaten by attacks like weaker projectiles can
*Several aerials landing cancel. Of special note, Fair walls Wario out really well with almost no lag.
*Wario has no CG on Link.
*Link can shield grab Fsmash and attacks with good shield push because his long tether grab.
*Link does have enough power to KO Wario without racking up a ton of damage.
*Link can live forever off the top of the stage. For example surviving Wario's Uair at 153% on Brinstar

*Link has a decent intercepting game with projectiles and close to the stage aerials so he can at least add damage.
*Most of Link's options can beat Wario's bike, air or ground.
*Link does well on many of Wario's good stages like Brinstar (when it was legal
) because his platform/camping game.
*Link has decent combo breaker options and Wario doesn't have options that murder Link for a ton of guaranteed damage like Sheik's Ftilt or DDD's CG. Link needs good reads though.
Link's cons (Wario's advantages)
*Wario has better weight, air movement and recovery.
*Link's grab has a normal situation ground release so Link can't pull grab release tricks like some characters.
*Wario also has power.
*As mentioned, Link is vulnerable offstage. Wario can gimp him many ways including a simple run off Nair
.
*Link's arrows and boomerang are easily eaten by attacks.
*Wario's Fart gets Link offstage if he's on and gimps crazy well if Link's off.
*Wario's crazy air mobility lets him jump circles around Link once he gets in.
*Wario's Fsmash armor wrecks Link's lag and wins hit trades.
*Wario doesn't have bad stages like Link but with recent stage list reductions (
) Link still can ban Frigate and do well.
*Link has a bad time trying to chase Wario if he has the lead. Wario timing Link out is very hard to deal with. Link is worse at timing Wario out because bad mobility and the offstage factor.
*Wario's faster/less lag.
It's about Link spacing and Wario trying to get in. Wario wins this game and has better payoff but not by too much. Link gets punished hard. Fart is a really annoying factor that hurts Link because Link's bad mobility/recovery can't get around it if Wario's smart. If Link plays smart it's an uphill climb but doable. If Link's stupid/predictable Wario wrecks him.
Kudos for keeping the MU discussions alive btw. Most characters can't.
