Temur Elevator Even without the citys blessing, Temur Elevator is still a 3-color pain land that I would be happy to run in a multicolor deck
Had I not been sent some packs to crack open, I know I wouldnt have pickup up any packs on my own - as someone who isnt looking to resell cards, play competitively, and just likes to enjoy casual games with friends, I couldnt justify that sort of cost
If you do have a way to reduce equip costs or even get one for free every turn Heartseeker is a budget option worth checking out
The only reasons it isn't higher are because it requires a costly six mana each turn to pull off, eating into resources you could be spending winning, and because needing two colours in your colour identity limits the decks it could fit into
I feel like the first creature to add kind of has to be Nesting Dragon, which checks all the boxes
