Hmm, fusion summon grandmerge, at the battle phase activate anti magic arrows, then destroy a monster with it, activate grandmerge, special summon storm neos, at end phase shuffle all cards to deck via storm neos, is this one of the right comboes besides flame wingman or shining flame wingman?
Yeah, it works, already tested it, it works for any fusion e heroes, in my case it was SFW, neos knight, storm neos, and thunder giant, so... I guess this card might be the one that e heroes needed to be tier 3 or probably 2 at best...
