Slifer's is all about having cards in hand to power it up and anyone trying to attack it will often find themselves 2000 ATK points weaker, Obelisk is about having monsters on the field to sacrifice to nuke the opponent's field and Ra can big itself up depending on the number of Life Points you have or you can sacrifice Life Points to destroy your opponent's monsters and if you summon it through the effects of The Winged Dragon of Ra Sphere Mode, you can get over Ra's weakness of its contradictory effects by having Ra at 4000 ATK points if summoned that way
While the Fairy type attacker, Xerneas EX (EX), was not that great, its support engine of Aromatisse () and "Baby" Xerneas were promising cards
Luckily, thats what the structure deck is for
Instead, I'm looking for Birds that truly stand out - creatures that have more creative abilities (that are still powerful, mind you)
Galaxy didn't specify the playstyle for this deck
What you're about to do is dangerous
