Sonic Warrior is meh.
Influence Dragon might be fun with Exploder Dragonwing.
And Crimson Blader seems like it'll stop alot of decks.
Except when people use Exceeds, then Crimson Blader turns useless against them.
Crimson Blader's effect activates when it destroys any monster (not just Synchro like the anime version)
but yeah its summon-stopping effect won't work on Xyz decks, unless the Xyz deck is made to summon Rank 5 or higher Xyz (they would need to summon lv 5 or higher monsters first to Xyz Summon a Rank 5 or higher Xyz, but they can't if Crimson Blader's effect is active)
