All I have heard is all the Bitching and moaning about The Great Mushroom Cloud, how it takes away from the game, how it prevents someone from winning, how it takes up TIME (sorry warparty) at tournaments at GenCon.
You want to know how to stop it... Here it is, free advice (not something I usually do) on HOW TO STOP APOCALYPSE (before I make my decision on if I am going to tone it down)...
Number 1
Elminster's Intuition: Mike Vacco returns (kinda) to this forum. Why not have some fun and pull it from the bastards deck before he even draws it.
Number 2
Cold Cup of Calamity: If he's drawn it, rape it from his hand with this nice cool drink.
Number 3
Rings of All Seeing: See #2 above.
Numbers 4 & 5 (you've got to get lucky with these)
Hettman: Discard it from his hand.
Nobody Wins: Discard it from his Deck
Number 6
Spite & Malice Rule card. You name Apocalypse, and it can't be played, PERIOD.
Number 7(and possibly the most fun one)
PLAY APOCALYPSE YOURSELF EARLY IN THE GAME!!!!! Yes, you don't like it, play it first with minimal stuff on the table and no one else can play it again during that game.
I actually contemplated doing Number 7 during the final game of the 2002 World Championships. I had it in hand in my first 5 cards along with Tasslehoff, the Bag of Beans, Medallion of Faith, Ancient Kalidnay. I knew that Dave (David Sparacio) was playing Apocalypse from the first game, so I was seriously contemplating playing it myself, so that if I went "Slappy on his A@#", he couldn't play it.
There you go, 7 ways to De-Mushroom the Great Mushroom Cloud.
