If you cast Sigarda, Heron's Grace after a board wipe, you can rebuild your board state slowly but surely with its activated ability that creates Human Soldier creature tokens
While not quite as oppressive (since your opponent still gets to keep one card after you cast a Wheel of Fortune), it's still devastating
While I do not think thats whats happening, I can see why others might spot some red flags in trying to make the game have such a wide appeal, although to that I would say these announcements feel more like a continuation of the direction Wizards has already been taking the game instead of some big new approach
These characteristics play a huge part in its high value and collectability level
Its price tag nearly triples that of second-place Sylveon ex, and honestly, it earns it
Each opponent loses life equal to that cards mana value.
