Target 1 "HERO" Fusion Monster you control; return it to the Extra Deck, then Special Summon from your Extra Deck, 1 "Masked HERO" monster with the same Level as that monster's original Level, but with a different name. (This Special Summon is treated as a Special Summon with "Mask Change".)
Here are the monsters you can summon with Form Change. You can also use them for Form Change’s cost and summon another Masked HERO monster. Since Form Change is a Quick-Play Spell you can do this at almost any point in the duel to maximize their effects.
Returns from field to Extra Deck / Returns from your field to your Extra Deck
Transformation Summons / Special Summons from your Extra Deck
The correct play is solidman mask change into dian, attack to special summon vyon and send a celestial to the grave, mask change vyon into anki, attack again, form change dian into blast, attack, use final mask change to anki to anki for game.
the other guy is right. your combo is correct though to have diane-celestrial(or any other dark destiny hero) attack. form change to anki, attack. and if you destroy another monster with anki then use the other mask change you'll get from attacking
I wish we would get stratos. having avion in the deck just to get blast seems redundant since there is no effect attached and its so weak. what we really need is nightshade for real synergy. maybe an added skill down the road?
