I was going to test that one last night, but I noticed I didn't have all the cards needed, so I settled for a feasibility trial of the Idle Idol one... here's a pic of me and three of them, showing that it
is possible.
And, just to be silly, I attacked with an Undine when I had zero blue lands... simply to see it instantly vaporize before the battle started.
Here are a few more I thought up last night:
Redline: Raise Red Cap's ability bonus to 400.
Cloud Nine: Have nine Cloud Gizmos on the map simultaneously.
The Abyss: Raise Undine's HP to 500.
Mass Grave: Raise Anubias's or Soul Collector's ability bonus to 500.
Saint Bernard or Cujo: Raise Drool's ST to 250 in battle.
Pickpocket: Steal 1,000 G with Amazon.
Hmm, I seem to be stuck in a pattern of raising stats and ludicrously high numbers. I'll try to think of something different next time.
