Evolve (Whenever a creature you control enters, if that creature has greater power or toughness than this creature, put a +1/+1 counter on this creature.)
Whenever one or more +1/+1 counters are put on Lonis, investigate that many times.
Whenever you sacrifice a Clue, put a +1/+1 counter on another target creature you control.
Lonis turns every creature that enters and grows it into a pile of Clue tokens, then converts those Clues into card advantage and +1/+1 counters across your board. You snowball value through evolve triggers and counter synergies, eventually overwhelming opponents with a wide, growing board or exiling Clues into massive card draw. The deck plays a midrange value game, accumulating resources turn over turn until you out-grind the table.
Add token and counter doublers (Doubling Season, Parallel Lives, Branching Evolution) and cheap or free Clue sacrifice outlets to push the engine. Include fast mana (Sol Ring, Mana Crypt) and protection for Lonis, then cap with a deterministic finisher like Craterhoof Behemoth or a Clue/token combo to avoid durdling. Tighten the curve with efficient evolve enablers and proliferate effects to maximize investigate triggers.
