Wildgrowth Walker and Enter the Unknown/Jadelight Ranger [Investigating]

Brakkis

When you cast Enter the Unknown on a creature, that creature Explores 2

Wildgrowth Walker should trigger (+1/+1 and you gain 3 Life). It instead does nothing.

Likewise, when Jadelight Ranger explores, it explores the first time and triggers Wildgrowth Walker. It then explores a second time and does not trigger Wildgrowth Walker (it also gives mana to the opponent if there is a match but there's already a thread for that).

I've seen that, too. Enter the Unknown doesn't trigger Wildgrowth Walker

In addition, Wildgrowth Walker does not trigger it's effects when a creatures explores at the start of your turn as part of the Second (Right) Node in Across Ixalan.
