White has access to the best permanent removal in the game with cards like Path to Exile, Swords to Plowshares, and March of Otherworldly Light to deal with permanents forever
The cardboard version's price is currently $45.91 at the time that I'm typing this, while the MTGO version is $11.01
This 4/4 with first strike and deathtouch lets you play an extra land each turn, punishes nonbasics from across the table, and can turn your spare lands or creatures into card advantage
Mostly you want to play this with Worldspine Wurm for three 5/5 tramplers at instant speed
That comes from my particular experience, but the card is probably better in more capable players' hands
Theres always the simple version, bouncing it back to your hand with Crystal Shard, Erratic Portal, or Cloudstone Curio
