Sadly, neither card was particularly all that exciting, either from a design or power-level perspective
Simply tap dear old Krenko and you get to add X 1/1 red Goblin creature tokens where X is the number of goblins you control
In reality, I didn't actually play blue decks at the Pro Tour, but I have enough Sigils and Starfields to threaten to resolve
However, thats not the case for the plethora of keyword abilities that appear on cards in Through the Ages
The power to spend two counters from it to essentially draw a card is immense when it costs no additional mana, and the fact that you get +1/+1 counters for lands or spells is the cherry on top, or was it the keyword soup
Adding the cant be countered effect to those spells is insanely good, and makes the Halfling compete for the top spot with the good old BoP
