Thats an outrageous bit of value attached to one of your characters and it also protects you against the classic one-two punch of the meta defining ruby-amethyst control deck of set two, which would wipe your board with Be Prepared and then answer the first character you play with a Lady Tremaine which would force you to sacrifice it
In other words, though someone might open a fetch land in a Dragonstorm booster pack, fetches will not be legal in Standard, the card games flagship competitive format
Youre only protected from things that specifically target a player , such as burn spells, sacrifice abilities, or discarding cards
Crypt Ghast and Nirkana Revenant are good choices as well because they can double your mana pool, and with Urborg, Tomb of Yawgmoth all your lands can work with this effect
