[Legacy] Ezuri / Sage of Hours, need to fill a slot

I'm messing around with making a (bad/casual) deck using the new Ezuri commander card and Sage of Hours. I realize that it is impossible to make this a competitive deck, so this is just a dicking-around legacy deck. That said, I am a spike at heart, so even though this is a Johnny project, I'd like to be as efficient as possible.

I have a shell as such, I'm a bad elves deck:

1 Craterhoof

2 Ezuri, Claw of Progress

2 Sage of Hours

4 Natural Order

4 Brainstorm

2 Ponder

4 Remand

4 Counterspell

4 Force of Will

3 Arbor Elf

4 Deathrite Shaman

2 Crop Rotation

4 Gaea's Cradle

4 Misty Rainforest

4 Wooded Foothills

2 Tropical Island

2 Bayou

2 Forest

2 Island

This leaves 4 slots to run something that will help me get to the 4 experience counters I need to play (or order into) Sage of Hours with Ezuri on the board to have the infinite turns lockout, at which point I can just play cards until I win with hoof or chump damage.

If there were a card that was "Instant - GG: put four 0/1 plant tokens on to the battlefield", that would be amazing. I know that's not a card. Does anyone have any suggestions?
