You mean, the beta Farseer? How can you expect good synergy? Even if some new card gets that ability, it would be a 4 for 6P. ST Handbuff will wade away in a week (if it hasn't already). It predates on Devotion and devotion has no place in Gwent now. Without GY hate, purify, heatwave, 3x Tall Punish and control cards, no deck can win (unless you are the aggressor like NR Mages or SK rain). But, even if ST gets 4 for 4 Farseer (boost self whenever a unit in your hand is boosted), it would still not make handbuff good.
Lets see how many ST appears in the open. My bet is 0. Last time I underestimated Spelletel. But with new super hyper mega ultra power creep cards and ST getting nothing (I know Torque is a great card. But it is irrelevant in this meta as it needs Devotion and Devotion ST can't do anything), ST would not see any play. My bet is, SK, NR, NG and MO to be the only 4 factions of the coming Open we will see.
