its a Hermit Druid on opponents, but you get their land, and it doesnt have to be a basic
Casting it for free and perhaps using an EphemerateEphemerate on it can wipe certain boards clear
Larger than Life: sweet buffing in any format at a reasonable cost
The larger your cardpool is, the easier it is to make a deck with the necessary sources of White, since you have access to even more good dual lands
None of this is likely better than Wilhelt, the Rotcleaver, but this zombie warlock might be a nice way to power down that deck while still giving you fun things to do, if thats on your radar
For example, Chief of the Foundry, Etherium Sculptor, Master of Etherium, Steel Overseer and Cranial Plating all reduce your spells or make them hit harder
