mtg arena card library Collector's Cage - The Big Score - Library of Alexandria and Sylvan

These cards are less good the higher power you go, but at most Casual tables where youre ramping in white, they do a great job of keeping your land count down to enable your ramp

Wins arent impossible with this particular Starter Deck and there is definite value here for players looking to play any combination of Sapphire deck

You dont even need to connect

Yawgmoth, Thran Physician targets your stuff, Glistening Oil becomes very interesting when you make its downside upside, and Sinister Gnarlbark and other blight cards tie things together from there

Pair it with Avenger of Zendikar or Guardian Project for serious value and control
