When Guru Pathik enters, look at the top five cards of your library. You may reveal a Lesson, Saga, or Shrine card from among them and put it into your hand. Put the rest on the bottom of your library in a random order.
Whenever you cast a Lesson, Saga, or Shrine spell, put a +1/+1 counter on another target creature you control.
Guru Pathik turns Lessons, Sagas, and Shrines into a steady stream of +1/+1 counters while digging for the best of them on cast. You play a Simic enchantress-style value engine, deploying chapter-based Sagas and Honden Shrines to grind card advantage, then funnel counters onto a single creature to close the game with commander damage or an overwhelming board.
Built-in card selection on every recast filters toward your best Sagas, Lessons, and Shrines
Sagas and Shrines provide recurring value and effects independent of the counter payoff
Simic colors give access to ramp, card draw, and counter synergies
Counters scale a chosen creature into a real Voltron or proliferate threat
Lesson/Saga/Shrine density in GU is shallow, so consistency suffers without careful list-building
Counter payoff targets 'another' creature, requiring a second creature to be useful
Slow, value-oriented engine that can be outraced by aggressive or combo tables
Removal on the counter-target undoes a lot of accumulated work
No built-in protection or evasion for the Voltron plan
