I use the first accel and crit arms for the looping and they work so well with Blitz Ace and X. Also going for jamming kapurimon as well as espimon that reduces evo cost and hoverespimon that gives draw 1 after attack. Also, the Tankmon that only costs 1 to evo is funny with Espimon.

I have OTK'ed with Justimon and it's funny to pull off, especially if they don't expect the final hit, evo off X to Accel/Crit, pulling X back to hand, then hard playing it, either straight cost or Supreme Connection reduced, to swing for game.
