Gavi, Vicious Cycler v1.1.OTJ (EDH / Commander) [Revision 78]

Ikora Commmander pre-con 'Timeless Wisdom' base.

This symbiotic cycling deck emphasizes card draw and token creation revolving around 'Gavi, Nest Warden' abilities, fueled by 42 cycling cards options. Hard-to-counter add-on triggered abilities on some cycling cards bring added value, including discounted tokens via 'Decree of Justice', free land wipe with 'Decree of Annihilation' and free counter-spell via cycling 'Decree of Silence'.

In play, first priority is assembling a card draw / token creation, positive feedback loop between Gavi and 'Rielle, the Everwise' or 'Ephara, God of the Polis'. 'The Locust God' and Ephara work the similarly. Additionally, 'Mindmoil' triggered by your instant spell casts draws out a fresh hand during opponent turns, generating tokens from Gavi or Locust God. Passive draw sources such as 'Mangara, the Diplomat' or 'Rhystic Study' work as well, each of which can be multiplied by 'Strionic Resonator' to hit double card draw potentially on any players turn. Consider additional card draw sources 'Desolate Lighthouse', 'Idol of Oblivion' or 'Dack Fayden' to keep the feedback loop running.

Use 'Fires of Invention' for free spells while keeping your mana up for second and third cycles on any turn which isn't affected by Fires conditions. Fires plus Mindmoil can trigger heavy card draw for Locust God, as can 'Reconnaissance Mission' and attacking with a locust swarm.

Planeswalkers: 'Dack Fayden' is early ramp fixing: take an opponents mana rock when he comes into play, or use his + ability to trigger Gavi. 'Elspeth Tirel' is a potential closer with her -5 clearing the board for a token finale.

'Zirda, the Dawnwaker' reduces activated ability costs, from 'Kher Keep' and 'Hoofprints of the Stag' token generation to infinite colorless mana via 'Basalt Monolith' and reduced cycling costs around Gavi's first freebie each turn.

Empowering the token swarm, 'Anointed Procession' doubles output, 'Brudiclad, Telchor Engineer' provide haste and allows a change of all tokens to your best type. 'Akim, the Soaring Wind' adds tokens and grants all tokens double strike. 'Divine Visitation' converts any token created into a vigilant 4/4 flyer and 'Elesh Norn, Grand Cenobite' can clear the path for a token invasion.

Due to prolific card draw, 'Approach of the Second Sun' makes a readily accessible secondary win-con from the side board.
