blue card digimon tcg Azulongmon [EX3-025] [Revision Pack Cards] You may digivolve 1 of your Digimon into 1 non Digimon Card Game: 10 Staples

Making this cost just double green doesnt sound totally implausible, and even if it only costs 5 or 6, its still a very strong play

But if it would be destroyed by battle or a card effect you can instead destroy any other card you control, including Spells and Traps

It also comes with Storm, meaning when you cast it, you may copy it for each spell cast before it during that turn, and you may select new targets for the copies

The Guardian of Faith is a particularly great card that allows you to phase out as many creatures as you like for one turn as they enter the battlefield

With Ace Specs coming out in Temporal Forces, like Prime Catcher [ Temporal Forces ], that would probably be a better use of this extra space, so dont forget about stuff like that too
