Satellite tournament #1 for CIS-2016 in St. Petersburg.

At the same time, attacking PiR for Num risks losing most of the army, since Moner has no TP and, by attacking PiR, he is highly likely to expose himself to Grechka.

Well, if we're going to theorycraft:

Moner is not afraid of Grechka — he buys off with Tactics (which was already tested a couple of turns earlier). Grechka is feared by Syra. Boxes scouted for at least 120 pit fiends for demonizing, which could have been easily stolen with Flight (one, if I'm not mistaken, behind the monks on my plane in a grass treasure zone, and the second on Inferno ground on the opponent's plane in an unclaimed treasure zone). Additionally, there are a couple more unverified meat boxes lying nearby that Moner hasn't checked (right next to them, through the wall from this zone, lies a ring for +health near the Griffin Conservatory). The Griffin Conservatory was in the plans; I was only unsure about the timing — it depended on where the opponent ran with his army (it would give me first speed with +1 speed from the treasure zone the opponent hadn't visited).
