I’ve in my palms the playing cards Contaminated Floor and Corrupted Roots. Let’s suppose that I goal a Forest for my Corrupted Roots. Now, if I forged Contaminated Floor on that very same Forest I’ve a doubt about which manner they may work.

1.- Two each Auras will stay hooked up to the Forest (now became a Swamp) as a result of Corrupted Roots entered first similar to auras do not fall off of permanents after they beneficial properties veil or hexproof and each results of dropping life will set off when the land is tapped.

2.- Contaminated Floor will remodel the Forest right into a Swamp. The land will develop into unlawful for Corrupted Roots and it’ll fall off of the brand new Swamp and solely Contaminated Floor will stay.

3.- Different I’ve not thought-about.

I believe the right is quantity two, as a result of it’s the identical factor when a white aura is enchanting a everlasting and it beneficial properties safety from that colour (even whether it is till finish of flip). On this circumstances the auras will fall.
