correct me if I'm wrong, but it may be possible to cause your opponent's Quitet to miss the activation timing for the field wiping.
When your opponent fusion summons Quintet, if you chain a card effect in response to it being summoned instead of it activating his effect then Quintet won't activate the wiping.
Correct or wrong? Because I did something like that against an opponent in my previous game.
Actually he did use 5 different spellcasters from the graveyard. But right after Quintet was special summoned I activated 2 quick play spells in response to Quintet's S.Summon. First was Majesty with Eyes of Blue, second was Legacy Clash.
A card only misses the timing if the effect says "when." If it says "if", it can't miss the timing. If it says "when", then if a card is activated right after the card effect is triggered, then it will miss the timing.
For current meta destroying the field is not worth anymore since most new meta have cards that has many effects and give'em more benefit and advantage when their cards get destroyed, And Quintet destructive activation effect easily get interupted by some traps like Karma cut and fiendish chain, And quintet can't protect himself by banishing, face-down lock, return to hand, lower its stats.
