If you’re playing a zoo heavy deck like that you need ways to continue to fuel your board and take advantage of your board.
I’d recommend 2-3 Spelljammers or Sojouner, with your curve capping off at 3 you NEED card draw otherwise you’re going to burn out very quickly. Spelljammer and Sojouner both draw you cards out of your own deck as opposed to generate cards, which is important because you’r playing a mech deck.
Try throwing in 2-3 Chasis of the Mechazor if you can. It’s a fairly good card that builds up Mechazor and extends your curve just a little bit so you don’t straight up burn out.
2-3 Inner Oasis/ 2 Feralu. These cards allow you to take advantage of the you board of cheap minions. Both cards can get a ton of stats with a handful of minions on board and snowball the game.
