This is due to the fact that it is the rarest MTG card
So, if you can defeat Invasion of Zendikar, you will end up with a 4/4 Elemental creature with vigilance and haste that is also a land that can tap for any color of mana
The two copies of Geier are there as hard to remove backup discard outlets, though we are only running two as they are generally inferior to our other land options, and we do generally want to push for double or triple black as soon as possible
With that in mind, its likely best to view this card as a form of card advantage as opposed to a hatebear that will keep your opponents in check
This card does nothing to hinder searches like Aven Mindcensor or allow you to steal them like Opposition Agent, which means that its both less likely to draw ire from the table and more likely to not actually prevent your opponents from carrying out their plans and winning games
