Caller summoning Infernal is absolutely disgusting, hell it's even great value if it just pulls a second Caller. Just went 10-3 off the back off 2 Callers, one Infernal, one Felguard (lol) and as much removal as I could possibly grab even though my curve sucked hard.Guys watch Trump's arena run right now, he has 3 Voidcallers and like 5 Dread Infernals.
