what do u use the 2 cramas for if u only got 2 rays? ???
The remaining ones can be used on Minor Phoenixes; they're perfect Cremation targets. Not only do they come back, but they do it the next turn (unlike when they're killed by other spells).
Unrelated to that, I also wish to add that Ball Lightnings instead of RoL's are awesome. If I get a Minor Phoenix out, I can Cremate that over and over instead of the Ball Lightnings, and get 5 damage a pop for those instead. It has allowed me to speed the matches up even more, and the satisfaction of doing that little extra bit of damage needed to win with a simple Ball Lightning is lovely.
