It is OK deck before ~4100. You can breed sentries to ~25, thin 30 cards deck to zero, brick Henselt/SD, destroy GSs and nekkers. Have fun with rng. But mandrake, Coral and shirru..
Maybe competitive rng should be removed from ranked? Like with inculsion rate above 20 with any leader. Really tired how elven scouts punish any non meta deck. Swarm with bomber, non-control with engine, weather with weather clear, weak engine with panther, scorch align with buffing units.
Maybe recon should be NG/NR card. You know, barbarians, elves and monsters are not bothering with military tactics much, they just "kill d'hoine", "eat it" and "lets die couple of times for SK glory".
I do not use mandrake at all, as cursed NR or hyperthin-sligthly_cursed_armor-Nova have no room for it (lately playing only them). I tried Bloody Flail to instakill Calveit, but then they just mandrake Roach, tried Vandergrift Blade which is too low tempo play for a counterplay and useless with...
Combo Cahir+Roach+Calveit(Mandrake)+(some other cards) in one turn R3
Does anybody else think that it is too consistent and strong combo in already good deck? My reasoning below.
Non interactivity
You can deny it only by mandraking Calveit if:
1) Calveit do not Mandraked on turn he played
2)...
You can try Ocvist to return CA. Nobody expect him in the middle of 2 round (of course, you should lure out removal with you engines). Worked well for me around 4k last season (but not NG, armor NR)
