There are enough payoffs for stocking your graveyard with lands, including Crucible of Worlds, Splendid Reclamation, and Cavalier of Flame, that a land-discard strategy isnt unplayable, though it might be niche
There will be situations where a player may not even attack with the 10/10+ creature because of combat tricks or blockers, because its incredibly easy to just mill a player out of the game after this thing boards without placing it at risk
The combination is a powerful token-making effect with a potential tutor if that suits the board state instead
I highly suggest taking a look at: Dawn of a New Age : Provides you with an additional draw each turn until counters run out and then life gain
While Jaya is no longer with us, you cant help but feel as though she were alive when you see a foil version of this card
The Great Henge is a big EDH staple that provides everything you want in a green deck: cards, life, and +1/+1 counters
