Skull Red Bird
Blue-Eyes White Dragon
4-starred Ladybug of Doom
Shard of Greed
Fortress Whale’s Oath
Mask of the Accursed
Fulfillment of the Contract
Burst Stream of Destruction
Magical Arm Shield
all depends of how you start the duel, if you are lucky enough you can summon since you first turn, if one of your ritual monsters dies you can bring it back with fullfillment of the
contract, and if you dont have monsters to sacrifice use one of your blue eyes dragons and then bring it back later with ascending soul, and if you already use all of the spell cards or you want to use another spell card again you just have to use hidden spell book and its all good.
Also u can use shard of greed and draw 2 more cards (you can use hidden spellbook and make draw 8 cards in total)
and use the vylon ohm monster to recover mask of the accursed or fullfillment of the contract
and for defense u only have mask of the accursed, trapp jammer, nutrient z, twister, and magical arm shield.
The ability its for when your about to lose (>1500 lp) and you need a fortress whale, so you use the ability and in the draw phase you get a fortress whale...
