SPELLSEEKER COMBO
--------------------------------------------------------
https://tappedout.net/mtg-decks/wizards-chess-1/

{2UB} mana available.

Cast Spellseeker {-2U}.
[ IT, SS ] {B}

Resolve Spellseeker, finding Culling the Weak. Cast, sacrificing Spellseeker (net {BBB}).
[ IT ] {BBBB}

Resolve Inalla’s trigger {-1}, finding Unearth.
[ - ] < SS_tok > {BBB}

Cast Unearth {-B}, targeting Spellseeker. Inalla and Spellseeker trigger.
[ IT, SS ] < SS, SS_tok > {BB}

Resolve Spellseeker trigger, finding Burnt offering. Cast on Spellseeker {-B, +BRR}
[ IT ] < SS_tok > {B BRR}

Resolve Inalla trigger {-1}, finding Finale of Promise.
[ - ] < SS_tok, SS_tok > {BRR}

Cast Finale of Promise, targeting Culling the Weak and Unearth. Cast Unearth first {0}, then sacrifice token with Culling {0}.
[ IT, SS ] < SS, SS_tok > {BBBB}

Pay for IT {-1}. SS tutors for Entomb. IT {-1} tutors for Reanimate.
[ - ] < SS, SS_tok > {BBB}

Entomb Scholar of the Ages {-B}, then return it with Reanimate {-B}.
[ IT, SOTA ] < SS, SS_tok, Scholar > {B}

Resolve Scholar’s trigger, returning Entomb and Burnt Offering. Cast Burnt Offering on Scholar, and Entomb for Shallow Grave. {-B, +7, -B}
[ IT ] < SS, SS_tok, Scholar > {6}

Resolve Inalla's trigger to return Burnt Offering and Shallow Grave. Now loop Shallow Grave and Burnt Offering to make infinite black and red mana and infinite hasty scholars. Can also loop Entomb to add every instant and sorcery from library to hand.


--------------------------------------------------------
INFINITE MANA WITH SIGIL TRACER + DRAMATIC REVERSAL
--------------------------------------------------------
Sigil Tracer on the battlefield and mana rocks that generate more than 1U, cast DR, use Sigil Tracer to copy. DR copy resolves and untaps mana rocks and creatures. Repeat.

--------------------------------------------------------
INSTANT-SPEED WIN WITH TEFERI + SIGIL TRACER + DRAMATIC REVERSAL + 2 WIZARDS ON BATTLEFIELD / ONE WIZARD IN HAND
--------------------------------------------------------
(Expensive, but instant speed. Less expensive if Sigil Tracer is already on the battlefield.)

Cast Teferi. Pay for Inalla trigger.
< Teferi, Teferi copy >

Cast Sigil Tracer. Pay for Inalla copy.
< Teferi, Teferi copy, Sigil Tracer, Sigil Tracer copy >

Cast Dramatic Reversal. Hold priority. With original DR on the stack, use Sigil Tracer to copy & generate infinite mana.
(Unfortunately you can't reserve the Inalla triggers and pay with the mana generated by DR.)

With original DR still on stack, cast Inalla.
[ DR ]
< Tef, Tef copy, ST, ST copy, Inalla >

This gives 5 wizards. We need 5 Wizards to activiate Inalla, and 2 to activate Sigil Tracer. So cast any wizard and pay for a copy.
[ DR ]
< Tef, Tef copy, ST, ST copy, Inalla, AnonWiz, AnonWiz copy >

Tap 5 wizards to use Inalla's ability. Hold priority and tap 2 to copy DR using Sigil Tracer's ability.
[ DR*, Inalla Drain, DR ]

DR resolves. Tap 5 to use Inalla's ability again; hold priority and copy DR again.
[ DR*, Drain, Drain, DR ]

Repeat.

--------------------------------------------------------
INFINITE DUALCASTERS ('SPLINTER TWIN') - 3URR
--------------------------------------------------------
(Top of stack is to the right)

Ghostly Flicker targeting anything; holding priority, cast Dualcaster. Stack DCM and Inalla triggers so DCM resolves first, copying GF. Target original DCM and (pain-free, untapped) land. (The first Inalla trigger may go unused, as this loop does not pay for the first trigger by itself.)
[ GF*, IT, GF ]
GF copy resolves. Land enters untapped, along with DCM. DCM and Inalla both trigger. DCM copies GF, targeting land and original DCM. Float a mana from the land that re-entered.
[ GF*, IT, IT, GF ] + {1}
As before, the GF copy resolves, the land and original DCM enter untapped, and DCM and Inalla trigger. Float {1} and use the original DCM trigger to copy GF again.
[ GF*, IT, IT, IT, GF ] + {2}
Repeat until we have {N} mana and N+1 Inalla triggers
[ GF*, IT, ..., IT, GF ] + {N}
Pay for N Inalla triggers to create N Dualcaster Mage tokens with haste.
