Today’s COTD is a impossible to move castle!
From G Trial Deck Vol. 10: Ritual of Dragon Sorcery (Release Date: December 9, 2016) we got:
Demon World Castle, Vorbeugen
Grade 1 | Normal Unit
Shadow Paladin | Golem | United Sanctuary
[CONT]:Sentinel (You may only have up to four cards with “[CONT]:Sentinel” in a deck)
[AUTO]:[Choose a card from your hand, and discard it] When this unit is placed on (GC), you may pay the cost. If you do, choose one of your units that is being attacked, and that unit cannot be hit until end of that battle.
“Moving a castle that has taken root is more difficult than breaking a mountain.”
[Editor’s note: Finally a PG for Demon World Castle.]
