I am playing a deck running "Essence Channeler" "Hinterland Sanctifier" "Lifecreed Duo" and "Raise the past. In the last game I played I cast Raise the past, bringing 3 copies of Essence Channeler, 3 coppies of Hinterland Sanctifier and 1 copy of Lifecreed Duo from my graveyard to the battlefield. The ETB effects started triggering and the game told me I had to take another action or the game would end in a draw. This is not an infinite combo, as the ETB effects stop triggering after a certain time - it is frustrating as this is my win condition and it should not end up being a draw as there is an end to the triggers. Please let me know why this has happened and if there is anything I can do to prevent it in the future
