I dealt 2.2 thousand million(approx.) damage to creatures on this node with spells and none of it counted towards the objective. If it is only supposed to count damage done creature to creature, it should be worded differently.
On the other hand, Bolas2’s 3rd ability now counts…sooo…yeah…
The only card I played that counted towards that objective was Swiftblade Vindicator even straight blocking did not count. Seems that maybe Berserk was the winning evergreen.
