Legendary Planeswalker — Bahamut
As long as Grand Master of Flowers has seven or more loyalty counters on him, he's a 7/7 Dragon God creature with flying and indestructible.
+1 : Target creature without first strike, double strike, or vigilance can't attack or block until your next turn.
+1 : Search your library and/or graveyard for a card named Monk of the Open Hand, reveal it, and put it into your hand. If you search your library this way, shuffle.
While Grand Master of Flowers is a creature, he is not a planeswalker. He cannot be attacked and damage dealt to him while he is a creature will not reduce the number of loyalty counters he has. However, you may still activate his loyalty abilities as normal.
