Each melo has a hidden mechanic:

-Aria gains half the health of her target on kill

-Piro gains half the attack of her target on kill

-Melome gains double buffs from campfires.

Each one can be stacked 3 times. On the third stack, they each gain a bonus sigil. Each stack applies a +1 to the blood cost.

Yes you can have Aria eat a giant card and gain like 20 bonus health, lol.

You must win the fight for Aria and Piro's to be kept permanently.

Each boss has a remixed gimmick:

Ash:

-Will steal Pokemon-tribe cards once every 3+ turns. After 3 turns, he has a 50% chance to steal something every turn until successful. He will only steal Pokemon cards.

-His second phase gimmick is he will trade all of his cards for yours. If he has nothing on the field to trade, he will trade you a (0,1) Magikarp instead.

Eggman:

-Theft mechanic works the same way as Ash, except he will steal anything. Mobian-tribe cards will be turned into an Infected Mobian, everything else will be turned into a Badnik.

-His second phase gimmick is a giant Rouge card. Don't get squished!

Midna:

-Theft mechanic is similar to Eggman's, except she has a 50% chance to turn the target into a Smothered Corpse or an Imp Simp. Smothered Corpses are terrain and are left on your side of the field, Imp Simps fight for her.

-Her second phase turns all her current cards into Smothered Corpses, and any empty spots are filled with Imp Simps. They are then all traded with you.

-Her third phase is a giant Melome. Melome steals half the attack of every card on the field when she spawns, and which multi-strike sigil she gets depends on how much power she steals (0-1 for omni strike, 2-3 for double strike, 4+ for single strike)
