You've just played land for turn. Kenrith failed a breach on the previous turn and agreed to stop as long as he could play Ashiok and Opposition Agent to stop Sisay from winning, he has breach in hand and over half of his deck in the grave. The other players are most likely going to push to win on their turns. There is only a tropical island untapped from Kinnan and they used chain of vapor already to pop the breach. there are a few creature in grave yards but nothing you can use from agatha's. Find the line and win on this turn.
