Didn't know you had it trademarked. Luckily the TC version relies on a 3 slot immortal thus avoiding any infringement issues.
It works better on defense though as i'm sure master IH has a few rain of stones scripted to take out the Supreme Prime Minister. But that would just lead me to prolong our fight by using some probing attacks first before sending in the SPM to get IH to waste gems and trigger spells that might damage his own troops.
