🏆 Jhoira's Treasure (EDH / Commander)

Combo's

Krark-Clan Ironworks with Myr Retreiver and Scrap Trawler:

Can go infinite if you have a cost reducer on the field. First sacrifice Scrap Trawler to get 2 colorless mana and (optionally) return any artifact of 2 cmc or less. Then sacrifice the Myr Retreiver for another 2 colorless mana. When it dies, return Scrap Trawler to your hand and cast it. Sacrifice Scrap Trawler again to return Myr Retreiver to your hand. Cast Myr Retreiver and sacrifice it to return Scrap Trawler to your hand. Repeat ad infinitum. You now have infinite colorless mana and an infinite storm count. This also draws your whole deck if Jhoira, Weatherlight Captain is in play.

Isochron Scepter with an imprinted Dramatic Reversal and some mana rocks:

As long as your mana rocks generate over 2 mana, you can tap the scepter to untap all your mana rocks and the scepter. This allows you to get infinite mana to cast spells, but it also allows you to use activated abilities on creatures or artifacts multiple times in a row. In some cases you even win the game on the spot:

• With Codex Shredder in play you can mill all the other players
• With Mystic Forge in play you can go through your library and exile the cards you don't like
• With Clock of Omens in play you can untap your artifact lands: Darksteel Citadel, Great Furnace and Seat of the Synod
• With Emry, Lurker of the Loch in play you can cast all of the artifacts in your graveyard
• With Master Transmuter in play and a way to create blue mana you can keep recasting the same artifact over and over again to draw your whole deck with Jhoira, Weatherlight Captain
• With Crystal Shard in play you can return all of your opponents creatures back to their hands
• With Lux Cannon in play you can destroy all of your opponents permanents, including lands
