Thor doesn’t really need meter so he’s pretty good as the first character. Then again Wolverine doesn’t really need it either and Wolverine is simple to play even at beginner level (which Thor isn’t).
By having Wolverine on point, you could help his game by choosing Mighty Spark assist for Thor. It’s a really slow starting projectile but I guess it’s better than Hadoken at what is does. For Ryu you should pick Tatsumaki for combo purposes. This team would be geared to fit Wolverine and the only way to play with Wolverine is blistering rushdown. If you get him killed your offense will be pretty much dead too.
Thor on point, Thor doesn’t really gain anything from Wolverine’s assists. I can only say that you shouldn’t pick Tornado Claw, just go experimental. For Ryu I think Hadoken might be good because Thor’s projectile is really slow and he needs at least some support to get in on the opponent. Tatsu might still be a good choice too. I think you should focus on calmer play with Thor on point, annoy the opponent with projectiles (not super effective), take it slow and punish accordingly. When Thor and Wolverine comes in you should switch to all rushdown. If Wolverine happens to die you should focus on defensive play and punish any mistakes with Ryu’s Shinku Hadoken.
Honestly speaking the team sounds kinda bad, but anyone can do damage in this game. Just find the ways you can DHC and get your combos down. Thor has some nice resets and Wolverine is a mixup/crossup monster while Ryu mostly just deals great damage without being that awesome…
