Urza, Chief Artificer Most of the time, youll be casting Urza, Chief Artificer just for 3 mana, thanks to its affinity ability, and while giving menace to other artifact creatures is nice, Id have loved for its final ability to be triggered on ETB rather than at your end step so you can blink it and endlessly create an army
Annihilator 3 is no joke, and this 9/9 with super menace is going to decimate any board that it attacks into
I also love the backup abilities on Conclave Sledge-Captain, which can throw around some +1/+1 counters and add more of them when the creatures deal combat damage to a player
At the same time, she can only revive cards with a maximum power of three
As a result, Delirium will likely be able to claim more surprise wins against unprepared opponents than the (relatively) grindy Energy
Even if they do, you gain life and draw a card, so not all is lost
