yugioh tag force 3 cyber dragon deck Complete Custom for Yu-Gi-Oh! GX My Blackwing Deck

The Room enchantment doesnt cost much life in a deck built around it, even turning into a clock

At least 1 foil card per pack with chance of Epic, Enchanted or Iconic

Fusion Duplication X TRAP Target 1 "Fusion" or "Polymerization" Normal or Quick-Play Spell in either GY

Assault Counter X TRAP Counter When a Spell/Trap Card, or monster effect, is activated while you control an "/Assault Mode" monster: Negate the activation, and if you do, destroy that card

Spellcaster/Effect LV4 ATK/1850 DEF/1500 By sending 1 "Eria the Water Charmer" and 1 WATER monster from your side of the field to the Graveyard, you can Special Summon this card from your hand or Deck

So, don't let this EV calculation be the only factor in your decision of whether to buy a box
