2. Activate Chromatic Orrery for 5, drawing at least 3 cards (more if you control permanents with the colors you're missing).
3. Tolarian Kraken triggers 3 times, targeting Chromatic Orrery with all 3 triggers.
4. Pay for the first trigger with 1, untapping Chromatic Orrery.
5. In response to the second trigger, tap Chromatic Orrery for 5 C.
6. Spend 1 for the seonc trigger, untapping Chromatic Orrery again.
7. In response to the third trigger, tap Chromatic Orrery for 5 C.
8. Pay 1 for the last Tolarian Kraken ability, untapping Chromatic Orrery.
9. Repeat from step 2 for infinite card draw and Near-infinite mana.
