Experiment Kraj + Devoted Druid + Kami of Whispered Hopes

Experiment Kraj

Devoted Druid

Kami of Whispered Hopes

How it works

1. Activate Experiment Kraj by tapping it, putting two +1/+1 counters onto Devoted Druid.
2. Activate Experiment Kraj using Devoted Druid's last ability by putting a -1/-1 counter on itself, untapping it.
3. Activate Experiment Kraj's own ability, putting two +1/+1 counters on itself.
4. Remove the -1/-1 counter and one of the +1/+1 counters from Experiment Kraj as a state-based action.
5. Repeat steps 2 through 4 any number of times, resulting in any number of +1/+1 counters on Experiment Kraj.
6. Activate Experiment Kraj using Devoted Druid's last ability by putting a -1/-1 counter on itself, untapping it.
7. Activate Experiment Kraj using Devoted Druid's first ability by tapping it, add .
8. Repeat steps 6 and 7 any number of times.
9. You may also activate Experiment Kraj's own ability any number of times instead of step 7, putting any number of +1/+1 counters onto creatures.
10. Once there are infinite +1/+1 counters on your creatures, you may activate Experiment Kraj using Kami of Whispered Hope's ability any number of times, adding infinite mana of all colors.

This brilliant loop centers on Experiment Kraj borrowing the activated abilities of both Devoted Druid and Kami of Whispered Hopes while they each carry a +1/+1 counter. Because Devoted Druid's untap ability costs a -1/-1 counter, and Experiment Kraj can naturally place +1/+1 counters to continuously cancel out those negative marks through state-based actions, you can endlessly untap Experiment Kraj to generate infinite green mana. Meanwhile, Kami of Whispered Hopes doubles the influx of incoming counters and translates Experiment Kraj's astronomically growing power into infinite mana of any color.
