That is a really nice list! could you just elaborate how the combo with Banishing Knack + Jeskai Ascendancy / Jeskai Ascendancy + Retraction Helix works? i have trouble to understand it. thank you

Griselbrand123 in essence, you in order to perform this combo, you need to have:

• a 0 mana artifact or an artifact that produces enough mana to pay for its cost, like Sol Ring or Mana Vault

• Kykar out on the field

• Jeskai Ascendancy on the field

• Banishing Knack or Retraction Helix in hand, with enough mana to cast it

In order of what you actually do:

1. Cast Retraction Helix on Kykar

2. Tap Kykar to bounce one of your 0 mana artifacts to your hand

3. Replay the 0 mana artifact. From here, three triggers will hit the stack as a result of you casting a non creature spell: Kykar generates a 1/1 Spirit token, the Jeskai Ascendancy trigger to untap all your creatures, and the option to loot through Jeskai Ascendancy.

4. Because Kykar is now untapped, you may tap him again to bounce the artifact back to your hand, replaying it and repeating this loop over and over again, generating infinite Storm, tokens, red mana, and practically the entirety of you graveyard.

Your library* my bad

Now I see. Thank you very much for your in-depth explanation. Looking forward to finish my own Kykar list.
