Limiting or eliminating a players access to mana doesnt have to be a nuclear solution
From Alpha , we got things like Armageddon (PL), Fireball (PL), Hypnotic Specter (PL) as well as a full playset of Swords to Plowshares (PL GD)
Here we have some generic good lands-matter effects and abilities
You can definitely find situations where sacrificing something with this can net you some nice mana to cast an artifact, but more often than not, the ability wont matter Doing noncombat damage isnt something that is entirely automatic in Limited, so that part of the card wont always be coming up
On top of that, every roll makes Wyll stronger with a +1/+1 counter
