Forum:Should I run 2 or 3 Citadels?

I'm currently only running 2 citadels of Endymion with one terraforming in my spellcaster synchro deck. (It can be found in the deck help section under the same name) should I be running 3 citadels or keep it at two. As it currently is I just have them side decked with field barrier when I face another field spell deck. Any suggestions on amount of terraformings or citadels, thank you Hand of Pain 16:12, 9 May 2009 (UTC)
