1 Reckoner's Bargain
This one ran across a cycle of gotcha cards that each had two words in their names that you got gotcha'ed if you said either of them (gotcha was a mechanic that allowed you to get cards back from the graveyard if you caught the opponent doing a prescribed thing and yelled out "Gotcha!")
Bloodline Bidding, Kindred Dominance and Everything Comes to Dust quickly come to mind as control pieces that double as finishers
Common cards are the most frequent that players will find in a booster pack, followed by Uncommon, Rare, Super Rare, and Legendary
There are a handful of creatures with useful enter the battlefield triggers, and worst case scenario, the blink will cause your lifegain effects to trigger so Hope can mill even more cards
I have a strong personal bias toward blue decks, in part as a reaction to many drafters favoring RW strategies
