Well, if you cast something targeting a warded creature and then don't pay the tax, it means a casting trigger happened and your spell ends up in the graveyard
Mystic Confluence, returning in Battlebond , is a great example of how a bunch of not-that-powerful options become extremely powerful when you are given choice and flexibility
This way is to run cheap one and two mana cantrips that will target Blanka, trigger the ability to shoot your foes, give him a pump, and then it replaces itself and then you can do it again and again with the replaced card drawing you more gas, and then you have a big fat creature for the turn and damaged players
Perfect for display but not legal for sanctioned play
Each pack is a surprise bundle of 10 cards, with a mix of common, uncommon, and rare cards
In such a deck you play with an empty hand anyways
