[mwcard=MW1Q02]Bearskin[/mwcard], on the other hand, should be perfectly fine once frost cards start actually coming out.
Lol. So, in approximately two years time it may become playable?
You joke, but the sad thing is, that estimate is actually generous. Assuming the Siren doesn't specialize in ice magic (which is somewhat unlikely, since she already uses normal water and mind spells), the Cryomancer probably won't come out for 3 or more years. Based on past releases and shared information, we already know Arcane Wonders' rough schedule for upcoming Mages:
1. Paladin vs Siren
2. Alt Wizard vs Forcemaster (artwork has been available for a long time online)
3. Shaman vs Illusionist (from episode 8 of Mage Wars Mondays)
4. Alt Necromancer vs Druid (based on previous releases)
5. Sorcerer vs Vampire (from episode 8 of Mage Wars Mondays; it's possible the Vampire Mage will come later on or be revamped/scrapped entirely)
Considering the recent releases have been roughly a year apart and the staff's attention will presumably be divided among Arena, Battlegrounds, and Academy releases for the foreseeable future, I'd estimate that Sorcerer vs ____ (the first expansion somewhat likely to contain a Cryomancer) will probably come out around November 2019. So yeah... that's depressing.
Back on topic, I'm surprised no one has mentioned [mwcard=MWSTX1CKC09]Giant Wolf Spider[/mwcard] yet.
