Toughness is a fine and strong mechanic to run with, but its much better done on other commanders like Arcades, the Strategist where you have access to blue and green instead of whatever other color you get with your background
Wilhelt Zombies Of all the Zombie commanders, Wilhelt, the Rotcleaver provides the most consistent value: a steady stream of tokens and an extra card per turn, while also being a Zombie himself to benefit from synergies
If tails, this attack fails
The main beneficiary of Struggle's ability is almost certainly Shroofus Sproutsire, the mono-green token commander that may not have a ton of recourse against a board full of blockers given the lack of additional colors
The real kicker here is the activated ability, which will end up putting four +1/+1 counters on two creatures you control
Dont worry, as this TCG is light, quick, and easy to learn
