Devil's advocate-
Comparing to just summoning 3 Bayous.
3 Bayous- Need- 1 mask, 3 8+, 3 bayous, 1 Do it like dis
Skeeter Summon- Need, mask, crow, 2 8+, 9+ (stuffed), and to make sure you get a moderate on the attack (cant really quantify)., possibly 2 do it like dis
So clearly the 2nd needs more of a perfect storm of cards. Lets say both are successful. What do you get for your effort.
3 bayous (1 extra SS for upgrade) vs bayou, Skeeter, stuffed, 2 cards. Given the increased card intensity we can say the 2 cards are a wash (mixed with the extra SS). So now we are looking at 3 models vs 3 models. Its hard for me to say the Skeeter/stuffed vs 2 bayous is even an upgrade. Depends on the need for significant models to do schemes/strats.
"cute" is the best word i can use to describe it. Too many moving parts to rely upon and there will be plenty of corpses (and in better location) for the taxidermist so the benefit of the "extra" stuffed piglet is turn 1 at best. I dont think doing this turn 3+ does much and Somer shooting is usually stronger.
I think the people who do it to get a piglet waste AP as well, so not really knocking the skeeter version, just like sammie summoning i think AP is best spent differently
In the end, i dont think id ever consider doing this in tourny and find the 1ss for the chance at a skeeter (when i could just get a piglet in its place) is mediocre .
If you enjoy it, and pull it off I am sure the extra skeeters can get annoying for the enemy.
