Check out my echoes of eternity spoiler for alpha clash. This card doesn't read overly powerful by itself but could be a pretty impactful role player if you are able to consistently use its ambush ability. 4 resources for a 5/3 that also lets you cheat an additional 3 resources is quite the deal.

Two pro tour champions face off in the finals of the calling singapore. Is this the first time that's happened?

From Life to Death can be a 1-cost removal spell if you don't mind spending a few life points on it. From Death to Life also seems quite powerful. Just ambushing attackers with this card on top of getting their trigger enter abilities while your opponent is attacking will really shake things up.

A new alpha clash set, a new cycle of powerful cards getting this sick golden treatment. The cost-reduction mechanics and being playable without setting them as traps means they will have a powerful impact on upcoming tournaments. My favorite is From Life to Death. 1/2
