Galvanic Discharge is a single mana of potent creature and planeswalker killing possibility
If you lose the flip, the damage Goblin Test Pilot dealt is dealt to you instead
squire1 I see what you did there XD but you might want to double check the line of text under the now 'Notable landwalk cards' title, it might still hint at what the title used to be =) Considering how long landwalk has been around I'm surprised that not even 1 planeswalker has had an ability that either gives or takes a landwalk ability or creates a permanent with a landwalk related ability
In addition to Urtet's ability which can be played before combat allowing you to untap and swing with massive Myr creatures, the deck features a number of different anthem and +1/+1 counter effects to pump your board including Master of Etherium, Steel Overseer, Urza Prince of Kroog, Chief of the Foundry, Myr Galvanizer, Tempered Steel, etc
Each one is the same basic land on the front and back, depicting a peaceful setting on the front and a more treacherous scenario on the back
