mtg locus cards Omnath, of All put a 5/5 red and green Elemental creature token onto the battlefield Omnath Locus Of Rage

Batterskull is much like the Wurmcoil, it is robust and meaty

Rally Whenever Ondu Champion or another Ally enters the battlefield under your control, creatures you control gain trample until end of turn

We'd have to make the tokens easy to write on, make it clear the tokens didn't "legend rule" each other, and add a lot of legendary-matters effects

In the rare case where the exiled card is a land card (probably because that land became a copy of a permanent while it was still on the battlefield), you won't be able to play it from exile

Theres a suite of excellent countermagic and instant-speed removal like Annul, Counterspell and Go for the Throat to ensure you call the shots on what happens on the battlefield

Like Dimir, Grixis is one of those color identities that cant help itself but feel mean most of the time
