pokemon tyranitar card 135/193 - Paldea Evolved - Evolution Set - 3 Lot This card is freshly removed from a pack Tyranitar Cards & Artwork |

Unless an effect allows you to play additional lands that turn, you can play a land card exiled with Hedron Detonator only if you haven't played a land yet that turn

If you really want to play with all of your cards, or just dont care about official competitive play, nobody is stopping you from continuing to use all of your cards, and there is even a new Infinity Constructed format that ignores the set rotations and has access to the full card pool

Let your children mix colors if they enjoy experimentation

1: Put up to two land cards from your hand onto the battlefield tapped

They also dont exist on the battlefield and presumably cannot be destroyed
