Noticed after new update, was playing Izzet Node in Rising Tensions, running Prism Array, that any and all Landfalls made were not disabling the opponents first slot creature, and were also not drawing 3 cards upon triggering landfalls.
I can +1 this. I observed this behavior while playing the Trial of the Planes: Blue. Both of us had Prism Array’s out and any landfall would fail to trigger any card draws. No creatures were out, so I couldn’t confirm that issue.
I will add, this seems to be a Landfall issue. So any cards that have and will trigger Landfall, are not working
Can also confirm that at least Prism Array does not trigger on Landfall
@Oktagon_Support
I can confirm that Kazandu Mammoth(ZNR) and Skyclave Pick-axe (ZNR) actually works fine, they both trigger their Landfall mechanic.
Also in one match i had both the mammoth and Prism Array in play and the mammoth triggered on Landfalls while prism array didn’t!
You can clearly see the angel isn’t disabled but the mammoth has been buffed three times from landfalls:
Adding Zendikar Incarnate to the list of broken cards, mostly because it doesn’t have the landfall ability.
It only needs a 3-gem match to trigger.
Can confirm. All my effect on match mechanics are non functional.
Phylath is working as expected
Seems to be only the BFZ landfall cards are broken
Hello guys,
