Reveal 1 card in your hand to the opponent. Depending on the card you have revealed, you can use each of the following effects once per Duel.
● Normal Spell Card: Send 3 "Evil HERO Malicious Edge" from outside of your Deck to the Graveyard. During this Duel, you can Normal Summon/Set "Evil HERO Malicious Edge" without Tributing. ● "Super Polymerization": Set 1 "Supreme King's Castle" to your field from outside of your Deck and add 1 "Evil HERO Malicious Bane" to your Extra Deck.
This Skill will only activate if you begin the Duel with a Deck that contains at least 1 "Super Polymerization," at least 9 monsters, and no monsters other than "Evil HERO" or "Elemental HERO" monsters, as well as an Extra Deck that contains at least 2 Fusion Monsters and no Fusion Monsters other than "Evil HERO" monsters.
From the 2 new skills that involve Super Polymerization, “The Power Leads to Destiny” and “HERO Alliance”, “HERO Alliance” is the superior one for the simple fact that it lets you search Super Poly. I know Malicious Bane is a powerful card, but it’s kinda worthless if you don’t have access to it most of the time.
