1.13 had 272 cards, seperating unupped and upped.
270 useable ones, discounting the unupped shards
137 if you don't include upgraded and unupgraded as 2 seperate cards, except for chaos power/seed.
The below is done from memory and the bazaar. This is just a rough estimate, though.
84+16+18+16+18+16+16+18+16+14+14+14+12=272
26 pillars 2 per, QT
30 weapons 2 per, then dagger/longsword/hammer
4 shards- Divinity, Gratitude
24 dragons
