Pentavus + Mana Echoes

Pentavus

Mana Echoes

How it works

1. Activate Pentavus, removing a +1/+1 counter and making a Pentavite token.
2. Mana Echoes triggers, adding C.
3. Activate Pentavus again, removing a +1/+1 counter and making a Pentavite token.
4. Mana Echoes triggers, adding CC.
5. Activate Pentavus a third time, removing a +1/+1 counter, making a Pentavite token, and leaving C floating.
6. Mana Echoes triggers, adding CCC, leaving CCCC floating.
7. Activate Pentavus' other ability 3 times, sacrificing the 3 Pentavite tokens and putting 3 +1/+1 counters back on Pentavus.
8. Repeat for infinite colorless mana.
