Absolutely no idea. Tomas hysteria must be a joke, that card is OK but not something to fanboy about.
Rolph ... Also no idea, if you run Gheist on non-bans modes, especially T2 then Rolph is your automatic staple. This might be confusion about market situation, Rolphie was hugely marketplayed by one big investor group and what I know they failed in their goals (this is just a rumor tho, but the market graphs show Rolph peaking over 10k in relatively short time half year back - so the rumor might be valid.). That would lead to situation where they (probably...) want to get rid of their cards to get part of their capital back - leading to big oversupply - so price of Rolph has come down a big deal beacause of this. So the abnormally low marketprice might be a factor to make the (wrong) assumption about Rolph's play value or simply these two different "values" (play value vs. market value) got mixed up.
I pick Wardom over Ralph to, but i really am a sucker for that 8 damage. but Ralph has his obvious advantages, and seems to be more popular.
Tomas however I dont like that much at all. He looks great on paper, but really does not have that much going for him.
