I really like how well she works alongside a card like Lashwrithe: sacrifice the equipped creature to get a number of 2/2 Zombie tokens equal to the creatures power plus the number of Swamps you control
You can also use it to fix your colors, snag some utility lands, or even just ramp
Thrakkus the Butcher works really well with your commander, Atarka, World Render, which gives all your Dragons double strike when they attack ultimately letting you hit for quadruple damage
With both cards I have the luxury of knowing how many owners it passed through, as the community is rather small
Mythical Island changed everything for this type
The fact that this card hits all players clearly makes it a Commander favorite, and despite seeing a number of reprints, its original printing retains an above-$6 price tag
