Branded Fairy Tail

Branded gives you a bunch of level 4 spellcasters... This came to me in a dream.

Also a bit of a meta call, as Fairy Tail's engine can turn opponents monsters to Spellcasters, making them ripe for Super Poly, and Super Duper can summon/send Luluwalith to turn any Fairy Tail into Weaver or Teller, summoning Incredible Ecclesia in the end phase for Albaz shenanigans on their turn. 

If you open BIHS or White Albaz, you simply normal him and get Incredible Ecclesia from your deck to either make Synchro Ecclesia for a Branded play and if you opened Genia, Caresia or Super Duper you can get 2 Spell Casters on the field to bridge into Fairy Tail.

Branded can give heaps of material for Snow and Lubellion can return a few of those cards back to deck in a grind.
