That said, considering it has to be against a creature and not simply target, means you wont be getting the benefit from hitting players themselves, or opponents can simply choose not to block with one of their creatures and that means no counters, but with spells like Duel for Dominance or Ents Fury that forces Wolverine to attack an opponents creature or enchantments like Fire Whip can mitigate this restriction pretty easily
To help offset that, the second ability is very powerful
Legendary Land Inventors' Fair At the beginning of your upkeep, if you control three or more artifacts, you gain 1 life
You get the iconic mana (fast rocks, busted artifacts, sometimes the Power Nine), the famous engines (Tinker, Reanimator, Sneak, Storm), and the kind of drafts where a good deck can still lose to someone doing something disgusting on turn two
So few people and collectors remember or are aware of this early rare item, that you won't find it listed in any other price guide than the PokGym's
