This is super busted. Compare Jousting Lance

For what it's worth, Bonesplitter is kind of busted. There's a reason why we haven't seen it reprinted since 2003.

It's not that either of these cards are too good. Not for constructed at least. It's just that in a draft, you automatically first pick Bonesplitter, presuming there isn't a bomb in the rare slot. If a card is almost always the best pick, then you aren't forced to make interesting decisions and draft becomes boring.

Bonesplitter seemed fine though, for where it was: surrounded by other great pieces of equipment in a set about artifacts. If this set features a lot of powerful artifacts, and especially powerful equipment, then maybe it's okay (since then it isn't a guaranteed first pick.) Risky, though. Definitely needs testing.

If this isn't always a windmill first pick, there's something seriously busted in your limited format. I don't think this set is meant for drafting, but power levels should still be respected.

Well, you might already have got a few... but yah; this is more than a little bit above the curve.

As for the rest of it - wave beam goes through walls. Representing that as first strike? Maybe? I could see trample as a possible alternative.
