It does a little bit of everything, gaining life so you can stabilize, producing mana, and even putting a clock on your opponents
Summon: Valefor You need multi-target removal in Commander to deal with three opponents worth of threats
So even if you suck at the game and lose every match, rather then opening a random booster and getting what you get, you can hand pick the cards you want
and a new Effect Monster from the line of Ash Blossom & Joyous Spring , negating the effects of a Special Summoned monster and threatening their Life Points
Since your opponent cant negate the cards activation with cards of the same type as those discarded (monster, spell, trap) it can stop an opponent from developing their board
