Whenever you attack a player, tap target creature that player controls and goad it. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.) Whenever an opponent attacks another one of your opponents, you and the attacking player each draw a card and lose 1 life.

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.

At the beginning of your upkeep, choose target opponent. Until end of turn, that player can't cast spells, you may look at the top card of their library any time, you may play the top card of their library, and you may spend mana as though it were mana of any color to cast spells this way.
