The Silent Game W
Enchantment
Whenever an opponent speaks, sacrifice The Silent Game and yell at him or her, "I told you kids to quit yammering!" Counter the next spell that player would cast unless he or she pays 2 and says "Sorry ma/pa/parental figure."
"Why Billy, the rules are quite simple. Just stop poking your brother, and I'll stop playing my Stasis deck against you."

As cool as that is, it needs some mechanical tweaking to make it work within the rules. (How can a permanent not have a controller? Do other control-changing effects overwrite it?) Here's a version that fits the templating better.

Answer card:
Unwavering Loyalty :SymGW::SymGW:

Expedition's End
Land

The urge to just name Balance or Ankh of Mishra is almost too much.
