Jenova is the most valuable player in my own Cleopatra deck, for example, and her open-ended qualifications mean you can run 40 lands and 59 Legendary Creatures of your preference, if you so choose
But it isnt as great on its own
It can even target itself to make its attack safer
If I attack again with Felidar Sovereign and my opponent doesnt block it, they take direct damage
The flanking mechanics of the world have to be keyworded, while the bushido mechanics are keyworded on a case by case basis
Seeing as youre playing Dinos, that will be most of them, so youre always going to be gaining three life and drawing a card when you play a creature, so long as this powerful card remains on the board
