Throwing a spell

Using your main hand just make a throw move to release your spell, we could make the spell come from different directions depending on movement, this could open opportunities to also take into considerations where to place shields, or if a shield is already in place use a spell in a direction to either break it or avoid it.

Holding a spell

Using your second hand, you could select a single card to ‘hold’ your spell, it could be an attack or debuff cards. The 0 stamina cards and the buffs can’t be held. The card held doesn’t count to your number of cards in hand.

Enhancing a spell

Combine the spells in your both hands to get a new spell, the result depends on the cards.

Discard the hand

If you have nothing useful in your hand, you could discard the hole hand and draw the hole hand again. It could be some movement downwards, like throwing your cards in a table.
