Bubble Bubble is a card which can fit into functional strategies to add a bit more explosive power to them. In order to take it, you already want to have a decent density of Poison cards in your deck. If it's working, it's a ton of damage, though.
This is mathematically the most effective poison card, but it can't be your ONLY poison card. Combine with lots of draw/discard to find your other poison cards first, or just use it with the Twisted Funnel relic.
Apply 3 Poison to a random enemy 3 times.
If the enemy has Poison, apply 9 Poison.
You cannot draw additional cards this turn. ALL cards in your Hand are free to play this turn.
Gain 5 Block. Block is not removed at the start of your next turn.
This turn, your next Skill is played an extra time.
