K so its sorta difficult finding out what the boxtoppers and prerelease promos were for the new set

SO far I have found Padma, Cassandra for the starter box boxtoppers

but what are the other boxtoppers and prerelease promos and what do they do?

the 2 are called

SC4-tower of souls

Shadowar-shadowar

go too THD or CSI for the card lists.

that cant be all of them.... cuz then what is stand off and the SCIV equivalent?

Stand Off and Summoning Evil are the pre-release promos.

Anyone noticed there are 4 cards in promo set SW2P according to the serial number whereas there are only 3 in SCIV1P?

Here

Box Toppers:
SC- Tower of Souls
SW- ShadoWar

Pre-release
SC- Summoning Evil
SW- Stand Off
