mtg trap cards Subtype: Trap, 20 cards Target opponent puts the top thirteen cards of his or her library into his or her graveyard. Ravenous Trap - Zendikar -

Not being able to sacrifice the stolen creatures is a bummer, but seems like a way to balance out a repeatable control magic effect

If you want to talk numbers, Id say 8-10 pieces of mana ramp is a good number to aim for, but thats very arbitrary

A short, sweet, and utterly devastating effect with a myriad of applications

To make things even better, it included some crazy powerful cards for the time like Dragons Fire and Alladdin, Heroic Outlaw a card that was used in every Ruby deck back then (and is still strong in my opinion)

Comforting Counsel is a nice fit here, giving the whole board a burst of counters while also triggering Blech if you have gained life that turn

No one needs me to tell them 10 times why Sol Ring is good after all
