Jenrik's Tower

As long as you control a Tamiyo planeswalker, activated abilities of Clues
you control cost {1} less to activate.
Whenever you investigate for the first time
each turn, add {c} to your mana pool. Until
end of turn, this mana doesn't empty from
your mana pool as steps and phases end.
"Tamiyo's work has been wondrous. I wish I could repay her somehow." --Jenrik
