idea for a special event/gamemode

Hide and seek, at the beginning of the game each player chooses a phobie from their collection to be the life linked phobie. They don’t have to play them right away but an amount of keys equal to the phobie’s cost will be locked in your vault until the lifelink phobie is played (eg. if you choose uni-corn and don’t play it, 2 keys will be locked from your vault until you’ve played it.) In this gamemode, the hearts cannot be damaged. The only way to beat your opponent is to destroy the phobie that is linked to their heart. There is no indication of which phobie is the linked phobie until it is destroyed either, opening up a lot of different strategy options.

I know there aren’t really any alternate gamemodes in the game right now but i think this could maybe work as a temporary thing, aligning with the class events
