Experiment Kraj + Devoted Druid + Branching Evolution

Experiment Kraj

Devoted Druid

Branching Evolution

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.

This ingenious loop turns Experiment Kraj into an absolute powerhouse by turning it into a repository of Devoted Druid's abilities. Because Devoted Druid can untap itself by placing a -1/-1 counter and Experiment Kraj can place +1/+1 counters to cancel them out, you create an infinite self-sustaining engine. The real magic that supercharges this interaction is Branching Evolution, which doubles every +1/+1 counter placed onto Experiment Kraj, allowing you to easily generate an arbitrary amount of green mana and endlessly grow your creatures.
