Mikaeus, the Unhallowed + Cryptic Trilobite + Viscera Seer

Mikaeus, the Unhallowed

Cryptic Trilobite

Viscera Seer

How it works

1. If Cryptic Trilobite has any +1/+1 counters, activate Cryptic Trilobite's first activated ability until it has no +1/+1 counters, adding CC that can only be spent to activate abilities each time.
2. Activate Viscera Seer by sacrificing Cryptic Trilobite.
3. Cryptic Trilobite's undying ability from Mikaeus triggers, returning Cryptic Trilobite from your graveyard to the battlefield with a +1/+1 counter on it.
4. Repeat any number of times.
5. Resolve all Viscera Seer abilities, scrying 1 each time.
