Game 1 was against a Guard gunline (cant remember his list a blob squad, lascannon team, heavy bolter team, autocannon team, vet squad, scions, yarrick, psyker..I think) and was my first game in about 5 months and first game with a non marine army. Ended up getting slaughtered. Just too much cover so all my shooting was rubbish and the dice just abaonded me. Was an eternal war mission and he ended up sitting on 3 objectives for the win. Wraiths took a ton of firepower to put down though.
Game 2 was against marines (captain, 2 tac squads, 2 scouts squads and a las pred) and went much better. Maelstrom this time which I personally prefer. Was the one with the vanguard deployment and 3 objectives (name escapes me). Turn 1 was fairely uneventful he podded his captain and tactical squad infront of my wraiths who did no damage to them. Next turn my doom Scythe came on and took out his predator I veiled my lord and his warriors over to the other side of the table which was what changed the game for me. Wraiths tied up his captain for the entire game I picked apart his units with combined fire and got some great cards. One of the best being the Necron specific hold all the odd/even objectives. I rolled even and already had easy access to 2 and 4 and then I managed to also claim 3 after shooting his scouts off the table which handily stacked with the generic hold any 3 objectives card for 2D3 objectives. Ended up winning 18-1
Game 3 was against Tempestus (he had a command squad, 4 units in taurox's and Valkyrie) and was nothing short of a massacre. Tactical Escalation mission this time. Put my wraiths up 1 side and 1 of the warriors with the ghost ark up the other. Held my Lords swuad back to claim my only card which was objective 5 which was in my deployment zone. He spent all his turn shooting at the wraiths which did nothing. Next turn both flyers game in and just started removing units. Night scythe dropped off the immortals and took out one taurox while the immortals wrecked another. Ghost ark took one down. Doom scythe was overkill here but thats not always a bad thing. Lords squad veiled up and shot at a unit while the other warriors moved up slightly anf got a few pot shots off. Wraiths charged a squad and took them out. I cant quite remember what objectives I claimed in that turn. Last couple turns were more of the same there was nothing he could do as he was spending so much firepower taking down the wraiths and he just couldnt. I multi assaulted his command squad and another squad taking out his command squad. I tabled him in turn 4 and scored a huge amount of objectives that turn. I had Thrall of the silent king along with slaughter the living, I had assassinate, psychological warfare and behind enemy lines giving me a total of 9 points from those cards. Finished him off in his turn and won 20-0
So after a shakey start (but hey have to lose your first game with a brand new army) they performed very well. Three fun games so now just need to get some more models painted up for some bigger games at the usual gaming night.
