First off, they always take the first turn
Despite my passion for Un- sets, I was not at all prepared for how large a role silver-bordered cards would play in my first year as a designer
The five cards play much better than the land in terms of functioning as a source of mana without turn restrictions
Within the limited realm of Fallout cards, its a powerful card, as there are a lot of counter mechanics at play in the limited set: energy counters, rad counters, +1/+1 counters (especially from Monstrous creatures), muster counters, and more
Notably, once Valki becomes a copy of another creature card, he won't have his own printed activated ability
Attack the turn it comes down, slip a powerful attacker in there for big damage
