IMO, the tier list will look something like:
TIER 1
Stage 1 Variants (lots of playable Stage 1s to choose from)
MewPluff Vileplume
Zekrom/Tornadus
TIER 2
Magneboar
Reshiphlosion
Gothitelle
Beartic/Vileplume
Yanmega/Magnezone
Horsemega
Ross' deck
TIER 3
Donchamp
Scizor (on the backburner until Kyurem is released)
Steelix (on the backburner until Kyurem is released)
RDL Rush
Reshiboar
Thank you! I totally agree with this.
