My advice is to try not to overload too much unless you have a protection spell, a way to bring back your enchantments from the graveyard, or youre close to finishing the game
With fetchlands and other deck searches being an incredibly common sight in MTG , it's an easy staple for blue decks that want to combo off Tong's triggers with ease
Cards like Ashnod's Altar, Phyrexian Altar, and Earthcraft are all-stars in Ghave
It gives you a cheap play and introduces additional combos with cards like Restoration Angel and Felidar Guardian
You lose a creature or two, now you are up by all those nontokens sacrificed
