The cards old wording allowed for some leniency in a way that you could get away with playing the card and responding to the sacrifice trigger by tapping it for mana
With its intense mana cost, I'd like to pair this with Ancient Cornucopia, so you can effectively play this on turn five and also gain some life in the exchange
Light-Paws doesn't negate this, but she does double the return on investment you get for casting an aura spell
With the next MtG set Ravnica Allegiance just three weeks or so away, spoiler season in full swing, its time to decide which guild Im going to be for the upcoming pre-release event, and look at some of the spoiled cards
If this was for first-week Standard, then there would be a very good argument to put Felidar Guardian up at the top of the list, but there is a very real chance that the card wont be legal throughout its time in Standard
