Banning unwanted elements - Round 1: Groups 1 and 2 (Stage 2)

[True Federalist (진정한 연방 주의자)]

There are thirteen named elements in groups 1 and 2 and I want you to vote to eliminate three so as to leave ten for stage 2.  In the event of a tie, the first tiebreaker will be to have as equal a number of each group in the next stage as possible. Voting will last at least three days for this first stage.

Stage two rules: Pick two elements to eliminate and one to give immunity to.  Immunity will last for the chosen element until used.
