To be honest I wanted to bring Elements in an RPG style of upgrading.
This card could provide timed rainbows, with your main element(s) coming out first and then your Castles coming out last for the extra finishing Silence, Improved Heal or Thunderbolt.
Manipul8r does bring up a good point though, 6 for 1 with deflag --is-- an issue, however by the time these bad boys come out, the enemy will most likely have already deflagged or stolen your other cards anyways.
Any suggestions on how to improve this card and have it fit in the limited textbox? ^_^
