yugioh duel links mako tsunami deck Complete Custom for Yu-Gi-Oh! I'm currently using this water

Dryad of the Ilysian Grove, Exploration, and Wayward Swordtooth are ideal for the role

Notably, if you arent in a dungeon and an effect instructs you to venture into the dungeon (not venture into Undercity), you cant start Undercity

The owner can recast it, but it's temporarily out of play, which can be a significant tempo setback for your opponent

(6/23/2020) If your life total is brought to 0 or less at the same time that a Devil token is dealt lethal damage, you lose the game before its ability goes on the stack

Of course, the fact that you can tune it to the situation somewhat helps as well

This is my favorite ninjutsu card for Type Four in this set
