how about try using Sharuum the Hegemon / Krosan Reclamation / Reconstruct?

oath her? out, maybe either your vault or key would be place in your gy, put into play, and assemble time vault / key from there.

Spell Pierce is a VERY NICE card in an Oath deck

possible plays:

turn 1 play a land int duress
turn 2 play orchard, moxen, cast oath, with Spell Pierce backup

gg from that point on.

hi smbdy_182, my deck has no Lotus Petal. and also, Glen Elendra Archmage is just a creature, not a Planeswalker thanks a lot!
