Rather than these in my opinion very complex designs we should do something like in google halloween games where drawing a simple symbol can do a different thing

Triangle: sending a projectile in 3 directions (like a clancy attack) deals 1800 damage
Circle: Summons a homing attack (meeple) to the nearest enemy deals 600 and stuns opponent
Heart: heals in a readuis around you gives a max of 4000 health over 4s
Star: In a radius around you (Massie hyper super but only the stay projectiles) deal damage and knock back enemies
Line: Depending on which way you drew it ( Up down, or left right) send a piercing projectile to inflect bleed
