Okay, I know its not a goblin or a goblin payoff per se, but Purphoros, God of the Forge decks in EDH are often built as goblin token decks, seeing as each token you put in play can dome your opponents for 2
So blink Cryptic Coat and you get another 2/2 until you hit what you want and blink that
For instance, Slifer the Sky Dragon scales with your hand size, great for draw-heavy builds, but underwhelming in faster archetypes
They can even take a legendary creature and turn it from being an OK or mid-range commander into a top tier, high powered commander
Its a great starter for beginners who like building strength over time while keeping the board under control
I'd highly recommend playing the free online Pokemon TCG Live game with the free deck to get use to the game flow and rules
