Check lands enter untapped if you control a land with the matching basic land type. Glacial Fortress checks for a Plains or Island. They pair naturally with shock lands (which have basic land types) and basic lands, making them reliable in two-color decks with a solid land base. Check lands are among the most reprinted dual land cycles, keeping prices low.

Strategy

Check lands are excellent in two-color decks where you run 8+ lands with the right basic types. They get worse in three-color decks where you may not have the right type on turn 2. Pair them with shock lands for best results. In Commander, they are a strong budget option but less reliable than in 60-card formats because the singleton rule means fewer basics.

Frequently Asked Questions

Are check lands good in Commander?

They are solid budget options. In a two-color Commander deck with 8+ basics and shock lands, check lands are reliably untapped. In three-color decks, they become inconsistent because you control fewer lands with each basic type.

What makes check lands enter untapped?

You need to control a land with the matching basic land type. Glacial Fortress needs a Plains or Island. Shock lands count because they have basic land types (Hallowed Fountain is a Plains Island). Basic lands obviously count. Triomes also count because they have three basic land types.
