This card has become very popular in Fusion-based decks, such as Thunder Dragons, since Cross-Sheep can Special Summon another Monster out on to the field
Each pack includes the two supplies most collectors reach for first: a soft sleeve to protect the card surface, and a rigid 35 pt toploader to add structure, support, and everyday protection
Since there are tons of different sets that can be combined, you should be able to respond to different broken plays from different sets if you want to win
Mostly thanks to Bolass Citadel also being a fantastic in Commander, the card is worth over $9
This can be a major problem for its survivability in combat, as well as for any synergies
I can't be the only Commander deck-builder who has put Urborg in a mono-Black deck or who initially thought about putting Yavimaya in a Mono-Green deck
