By using the Tea's Holy Guard skill, you can use the effect of a Yomi Ship actively. During you turn, get a Yomi Ship to attack an attack position monster that has higher attack than that of it. The Yomi Ship is destroyed in a battle, and the monster that defeats the Yomi Ship is also destroyed. You do not receive battle damage for the effect of Holy Guard skill.
How to get
[Holy Guard] You receive no battle damage during your turn.
Even more underrated as it seems, this card is a great econ bait and even a mirror wall counter! If your opponent has only one monster on the field and you can special summon this with Hammer shark, you can attack with yomi ship for either a guaranteed 🔥 or a wasted windstorm/econ/risk-free mirror wall.
