Those two are definitely good cards, one is the nuke leader for PHY, which for now is still an effective tactic, and the other has an attack-all super after Dokkaning, invaluable for World Tournaments (the SA level needs to be high in order for it to be really useful outside WTs, but it's still pretty good).
But in general, a recurring joke / complaint in Dokkan Battle is how Vegeta cards always get shafted.
I'm finding his STR SSJ3 card really effective. Tank 80% damage for 7 turns and 50% chance to stun on Supers? I'm loving it
