Yurix, the Hedron Forge

Landfall - Whenever a land enters the battlefield
under your control, create a colorless artifact
named Hedron Shard with "When this enters battlefield, you may exile a target creature until
this artifact leaves the battlefield. (That creature returns under the owners' control.)"
Yurix, the Hedron Forge gets +1/+1 for each
Hedron Shard you control.
