I had been out of the MTG scene and have never been super-active but I enjoy the game. I recently played against a couple of decks with cards that included the ability Invincibility.
What are some deck building strategies to combat this ability?
I'm assuming indestructible right? For example {Gideon, Ally of Zendikar}
The best way is exile so stuff like {Anguished Unmaking} is great.
{Grasp of Darkness} works too (if the creature is small enough) but note say you block an indestructible 7/7 with a 5/5 and grasp of darkness the 7/7 before dance neither creature dies bc the combat damage isn't relevant due to indestructible.
{To the Slaughter} and sac effects work as well it's just harder bc if they have multiple creatures then the sac effect is awful.
Lastly is to stall so stuff like {Clutch of Currents} to bounce the creature work too :P
