In short, Rose gets big quickly
I have chosen mostly (but not all) cards which are specifically good in all-Zombie decks, mostly (but not all) based on their potential in Commander, and mostly (but not all) with present day performance in mind rather than historic achievement
Tweaking mana base now that I decided to get the shocks and stuff
Some popular cards to bring alongside Gengar ex in the place of the Drowzee line or Jynx are: The Pidgeot line , for the Drive Off ability and secondary damage Kangaskhan , for cheap, stacking damage Farfetchd , for cheap, early-game damage Mewtwo , for a heavy-hitting attack Mewtwo ex , for strong damage output An additional Red Card Supporter , for further control over your opponent Adding Dark-type mons like Zubat and Golbat into the mix can also be interesting, helping to mitigate any tricky type match-ups and providing further damage
The biggest tension is deciding whether youll be playing a monocolor, two color, or three color deck, since Lochthwain Paladin, Ardenvale Paladin, and Embereth Paladin (plus the hybrid uncommons) have stringent color requirements
The scarcity of the Special Tournament Promo print run is key
