Gavi, Nest Cycler (EDH / Commander)

This deck is meant to have friendly games with lot of interaction and creature-based decks, so it doesn't include infinite combos (like Curiosity-like cards) or very abusive moves (like Sundial of the Infinite), here is the plan:

Start by ramping and casting ceycling payoffs and cycle all the rest only to reuse them again with Abandoned Sarcophagus, Warden of the Eye or Rooting Moloch.

Deffend yourself by blinking attackers with Astral Drift and Astral Slide or exiling our own important creatures to protect them while sometimes reusing the ETBs like Warden of the Eye, Solemn Simulacrum, Cloud of Faeries or Rooting Moloch. With counterspells we can protect ourselves from big threats.

For finishing the game the main strategy is to slowly deal direct damage from our finishers or to buff all our tokens with Cathars' Crusade.

To make the deck more competitive it'd be as simple as take out this finishers and add Curiosity and Ophidian Eye with Glint-Horn Buccaneer, Niv-Mizzet, Parun and Niv-Mizzet, the Firemind. Also Brallin, Skyshark Rider would become a combo piece.

Actualisation: testing a surprise Scroll Rack from a draft in the place of Slide and Dice to see if it helps wheeling. Also testing Sea
