weight of a yugioh card YU-GI-OH! - Magical Dimension (YSYR-EN033) - Starter Deck: Yugi Reloaded - 1st Edition 200 Pack Card Sleeve Compatible

Your opponent can cast instants and activate abilities

It stands as one of the most elegant cards in the expansion, so it is not too much of a surprise that it is also one of the most valuable cards in Obsidian Flames

Spirit-Sister's Call allows you to sacrifice a permanent at the beginning of your end step to replace it with a permanent that shares a type with it: creature, Planeswalker, land, enchantment, or artifact
