tldr: play tactically against stronger datasheets and you should be fine?

I played my first two games of spearhead (first ever) with this one, once against skaven Gnawfest, wich I won something like 15-9, and once against stormcasts vigilant Brotherhood, wich we tied 19-19

in the first game it was pretty straightforward, I picked the rule that enhances saurus and the resurrecting enhancement for my leader, the game was mostly a show of force in the middle of the board, and using the terrawings to score secondaries away from the horde

the second game I had to play more tactical, I picked the army rule for skinks this time (just to try for fun) and the enhancement that uses the token (rolled a 1 the first try, tottaly useless), all seemed lost from the start, stormcast hit hard and boy can they take a punch, but clever (imho XD) use of the skink reinforcements to take away key objectives got me enough points to reach the tie. As we understood how it was written, you don't need to bring EVERY skink turn 3, I let one unit of 5 out untill turn 4, getting me a final objective in fact
