Planes usually have two important parts: A main ability which can be a continuous effect, such as Tazeem in Zendikar (whose ability is that creatures can't block while this plane is active), or a triggered ability, such as Undercity Reaches from Ravnica (which allows the controller to draw a card each time one of their creatures deals combat damage to a player)
What Is A Cube In MTG
Cheat in Yawgmoths Bargain and pay 36 life (just enough to keep you out of range of a Lightning Bolt), and you have a huge amount of your deck in your hand straight away
To do this, you need to have him equipped with things that you wont be detaching, so you can benefit from their effects
This is a solid amount of damage, one that can take out most evolving Basic Pokemon
All of these aspects come together to create a great portrayal of a Houndoom in natural Pokemon environments, standing proud and likely protecting its territory - just waiting to strike if needed
