Boast — : Target player searches their library for a card, then shuffles and puts that card on top. (Activate only if this creature attacked this turn and only once each turn.)
Attack with Varragoth, then Boast to tutor any card to the top of your library each turn, turning a 5/4 deathtouch beater into a repeatable Vampiric Tutor on a stick. You leverage that consistency to assemble a combo, a voltron kill, or simply stack your draws toward bombs and removal while grinding the board.
Repeatable, color-flexible tutoring every combat for whatever the situation needs
Cheap 3-mana body with deathtouch makes it a real threat and great blocker
Mono-black gives access to elite tutors, removal, ramp, and recursion
Boast can target opponents to deny them their best card or fill graveyards strategically
Tutors to top of library, not hand, so it doesn't generate card advantage by itself
Requires attacking to Boast, making it vulnerable to removal and creature-light board states
Mono-black struggles with enchantment/artifact removal and lacks evasion without help
High threat assessment—gets targeted by removal before you bank value
Converts Varragoth's top-of-library tutor into immediate card access by drawing the stacked card.
Add fast mana (Sol Ring, Mana Vault, dark rituals) and protection like Lightning Greaves to ensure Varragoth survives and Boasts early. Lean into a tight two-card combo backed by your tutors—Demonic Consultation/Tainted Pact plus Thassa's Oracle is the most efficient—and include card-draw enablers like Sensei's Divining Top or Bolas's Citadel to immediately cash in topdeck tutors. Round out with premium interaction (Toxic Deluge, Imp's Mischief) to defend the combo turn.
