yugioh dark hole dragon deck AGOV-EN020 – Aus Ygo Dark Hole - Yugipedia

Islandwalk and sea creatures are probably one of the only places where landwalk is remotely relevant these days, so I see this as a possibility

Cards that allow us to repeat these effects will see increased play

The first tournaments in 1997 and 1998 did not have any custom cards, and the 2000 (Autumn) Invitational used regular Magic cards with modified casting costs

Cards like Courser of Kruphix and Tireless Tracker are exceptional here but will be snatched up by any green deck, so it might be good for some of those payoffs to demand/reward a stronger commitment I'd consider Wayward Swordtooth as a more balanced version of the extra lands effect with a subgame that's fun and attainable (and not just by you!) #3 I think Simic Lands is a great archetype that won't be leaving my cube any time soon
