Rattle

Calcify

Calcify adds flat damage to every one of Osty's attacks, which significantly boosts the total output of Rattle's multi-hit strikes. In a turn where Rattle hits three or four times, this power effectively triples or quadruples its value.

Fetch

Fetch provides a cheap way to trigger an Osty attack while maintaining hand neutral through its draw effect. Using Fetch early in the turn ensures Rattle starts with at least one additional hit while digging for more low-cost Osty actions.

Bone Flute

This relic grants block every time Osty attacks, turning Rattle into a potent defensive tool as well as an offensive one. Because Rattle hits multiple times, it triggers the block gain for every individual strike, providing massive survivability during high-damage turns.

Sic 'Em

Sic 'Em marks an enemy so that every Osty hit Summons 2, which synergizes perfectly with Rattle's multi-hit nature. This combo allows the player to rapidly rebuild Osty's HP shield while simultaneously dealing high damage.

Right Hand Hand

Since this card returns to the hand whenever a card costing 1 or more is played, it can be used to chain multiple Osty attacks in one turn. Each play of Right Hand Hand increments the hit counter for Rattle, leading to an explosive finishing blow.
