you may play that card this turn mtg Do I have to pay the CMC for the exiled cards or if an opponent loses life then I can just the card? : r/magicTCG Conduit of Worlds — Phyrexia:

in fact, the standard casting only draws you one card, which means its closer to card selection

Seeing heavy play in Standard, the Elder Dragon enters with a Treasure token, with the option of casting Instant/Sorceries off your artifacts

One particularly damning thing to note is this chart: This table shows that with 7 Swamp and 7 Plains, you will have the required Plains to cast a turn-3 Territorial Hammerskull only 85.9% of the time (on the play, in absence of mulligans or card selection)

Its not as explosive as Exploration, but it plays into the late game much better

Until end of turn, target creature gains trample and gets +1/+0 for each card you've drawn this turn
