Very, very few cards in the game stop you from casting Generous Gift, so lets set aside the power of the card itself in the review and interpret that word a different way
The current release includes all of gens 1 and 2 (but with corresponding Fairy types)
Anax and Cymede Anthousa, Setessan Hero Ashiok, Nightmare Weaver Bident of Thassa Bow of Nylea Daxos of Meletis Elspeth, Sun's Champion Erebos, God of the Dead Hammer of Purphoros Heliod, God of the Sun Hythonia the Cruel Medomai the Ageless Nykthos, Shrine to Nyx Nylea, God of the Hunt Polukranos, World Eater Purphoros, God of the Forge Spear of Heliod Thassa, God of the Sea Triad of Fates Tymaret, the Murder King Whip of Erebos Xenagos, the Reveler
The designers had noticed that cats were a popular creature type with almost zero support
I found the artifact count to be quite high (17) for a deck that doesnt really provide any artifact synergy, and because of this, the precon only seemed to have room for one enchantment
5: Put target creature card from a graveyard onto the battlefield under your control
