Experiment Kraj + Devoted Druid + Shang-Chi, Martial Mentor

Experiment Kraj

Devoted Druid

Shang-Chi, Martial Mentor

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 clever loop turns Experiment Kraj into an ultimate engine by letting it borrow the abilities of Devoted Druid while Shang-Chi, Martial Mentor supercharges its growth. Because Experiment Kraj gains every activated ability of any creature with a +1/+1 counter on it, it inherits the Druid's ability to tap for green mana and untap itself by placing a -1/-1 counter. Shang-Chi, Martial Mentor steps in as a phenomenal amplifier, doubling the +1/+1 counters placed during the process so that Experiment Kraj can rapidly accumulate infinite counters and infinite green mana.
