Leonardo Da Vinci is a really cool card. I like the full art and I don't dislike the idea of having a cool historical figure in my cube, BUT I can't run it. The reasoning that I see it as the next level of a spreading disease. I'd call 40 life sickness. This disease infests every card that has been designed with commander as the primary format for it in mind – which feels like 90% of cards these days tbh. And since 40 life, or 120 lookig at all opponents, is a lot, everything has to be very well statted. Even creature like Leonardo here that you'd clearly include for their (tap) abilities, just so it is not nothing when they happen to be able to attack at some point. But here it is especially egregious. Blue is not the color where beefy beatsticks are at home, blue should NOT get centaur coursers with upside, that just NOT what blue is about.
It's not the first (or second or third) time of course,
God-Eternal Kefnet has been out there for many years now. But here it is especially bad, because there is no flavor justification at all. Like wtf, Da Vinci was not exactly famous for being a great fighter that could kill bears and live.
There is NO reason this Da Vinci card should be a 2U 3/3, EXCEPT it plays slightly better in this weird format that barely resembles MtG.
Rant over.
