1

   Prerequisites

What do I need to start this combo?
Doubling Season on the battlefield.
Oko and Spark Double in hand.
5 available

   Steps

How does this combo work?
1
Cast Oko by paying 2, causing it to enter the battlefield with six loyalty counters due to Doubling Season.
2
Cast Spark Double by paying 3, choosing to have it enter the battlefield as a nonlegendary copy of Oko, and to enter the battlefield with eight loyalty counters due to Doubling Season.
3
Activate an Oko's third loyalty ability by removing five loyalty counters from it, causing you to create two token copies of each other nonland permanent you control.
4
If you created any legenedary tokens this way, put all but one of them into your graveyard due to the legend rule.
5
Repeat from step 3 using a different Oko.
6
Once you have infinite Oko tokens, you may instead activate Oko's other abilities.

   Results

What do I get from this combo?
Infinite copies of nonland permanents you control
Infinite creature tokens
Infinite draw triggers
Infinite looting
Infinite self-discard triggers
Near-infinite card draw
