District Guide doesn't 'cantrip' with a full hand.

Gargoyle

District Guide, if played from a hand that has 6 cards, will fail to grab the relevant Gate.
As creatures leave the hand before they enter the battlefield(at least they always have in classic MTG) I can only assume this is a bug. Logically there should be space for the Gate as she has left the hand to be played and there are now 5 cards remaining.
It may be because the ability is two-phase; it fetches the land before charging it. Something about the sequence seems faulty. Like it looks like it attempts to grab before she appears on board.
