It was the early 2010s, and I was just getting starting to watch streams and videos of the Star City Games competitive Constructed circuit
Emet-Selch, Unsundered // Hades, Sorcerer of Eld Rarity: Mythic Rare TYPE: Legendary Creature // Legendary Creature SUBTYPE: Elder Wizard // Avatar CMC: 3 Mana cost: USD: $7.92 EUR: 7.87 TIX: 0.23 EDHREC RANK: 6600 (2/4) Vigilance Whenever Emet-Selch enters or attacks, draw a card, then discard a card
Destroying everything that comes in on a given turn is a good way to counter decks which plan to win with a mass of creatures
As that has the upside of untapping all the creatures
It is a really strong card, and playing any deck that's playing Tamiyo is likely to be good
Obviously they will not have sufficient mana in their next turn to just recast the spell in question and so they will have a dead draw coming their way
