Great H2H event mode - regular games with only 4 wins needed per tier - not 10 win sweat fest- and no random scoring, x factors, etc
Alot of big names got cards - and no outrageous OOP players
Shapeshifters were really fun also
Upgradable players with Candy was a great strategy also
And no super ability discounts or built on x factors - OVRs were the main thing that mattered
Then a huge LTD price crash at the end made everything affordable
