too bad you dont have wolf knight, giant spider, green slime, lady anariel, naga queen either of em would help with a psion deck
ugh i did a lot of testing (as i never got psion early game, didnt know any early game single psion teams)
turned out with something like this:
(that worked nicely with the traits i listed, not sure how bad it could go without it)
golem (traited till stoneskin - stoneskin mandatory)
valkyrie (fully traited)
druid (traited water link)-he is there nearly only for that water link, you might just as well put here a duplicate of traited valkyrie (or something else with water link perhaps lance knight) if u cant get druid traited, he still picks the green and does damage but the extra +1 blue mana i find more important
leonis banner +2blue +1yellow -1green
whole team would turn out with a +4 blue +1yellow -1green bonus
tactic for this would be:
-ignore golem, he is a meat shield that will take skulls on himself, could cast him in case the explosion could lead you to some extra turn, or when you need very little mana for valk/psion but there are no matches then the explosion could make it off a scattered gems of chosen color.
-just try to get directly mana for psion or valkyrie, mostly just happily matching blue gems for the extra mana bonus, taking all the extra turns you can
-obviously when you cast valkyrie make sure she will create an extra turn with the blue transformation, and take notice that every separate gem match will gain all the flag/trait mana bonuses so a few of 3 gem matches could actually net a lot more mana then a single 4 gem match
you could try with another tank not a golem but after you trait ANY unit with a stoneskin 50% skull reduction trait you will see it is very useful. i prefer golem here (even as it has a little lower stats) be couse it simply doesnt block you any mana and is cheapest to trait. knight coronet is also very good but then you just use it as an attacker - it will oviously take away a lot of mana from psion so they arent a good synergy. for the time being when you dont have any traited stoneskin tank, a leveled class hero is one of best choices for a meat shield.
i understand that early game usually u dont trait anything and struggle to do so but i think being able to fill psion mana with 2 or 3 gem matches early game as you rarely ever gain surge would be amazing. let me know how possible is that for you and what you think of it!
maybe ill find some other solution later on, need a break now =)
