Underdark Beholder

{4}{B}{B}

Creature — Beholder

Underdark Beholder enters the battlefield with ten eyestalk counters on it. If Underdark Beholder would be dealt damage, remove that many eyestalk counters from it instead. If you can't, sacrifice it. Whenever Underdark Beholder attacks, reveal cards from the top of your library until you reveal an instant, sorcery, or enchantment card with converted mana cost less than the number of eyestalk counters on Underdark Beholder. You may cast it without paying its mana cost. Shuffle your library.

Rulings

2019-11-12 If Underdark Beholder leaves the battlefield while its last ability is on the stack, use the number of eyestalk counters it had before it left to determine what converted mana cost to look for.

2019-11-12 If a spell has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

2019-11-12 If you cast a card “without paying its mana cost,” you can’t choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs, such as that of Tormenting Voice, you must pay those to cast the card.

2019-11-12 Underdark Beholder’s second ability isn’t a damage prevention effect. It can replace damage that can’t be prevented.

2019-11-12 You must cast the revealed card while Underdark Beholder’s triggered ability is resolving. You can’t cast it later in the turn.
