Strategist's Undertaking

When Strategist's Undertaking enters play, investigate twice.
At the beginning of your upkeep, choose one:
• Pay {1}{w}. Until your next turn, Clues you
control become 0/3 Construct creatures with
defender in addition to their other types.
• Pay {1}{u}: Until your next turn, abilities of
Clues you control cost {1} less to activate.
• Investigate.
