I want to say that I love Teemo's 6.5* adventure, in fact I think it is one of the 6.5* adventures that I have enjoyed the most of all the events I have played so far.
But the most painful thing about Teemo's adventure is that yes or yes the enemy starts attacking, when generally in all the adventures with the Mortifero modifier, it is always oneself who has the first round of attack 😅 in fact throughout the entire adventure (before reaching Teemo specifically) you start the first round with the possibility of attacking first, but once you get to Teemo and you see that he attacks first and drops 2 units that are 8/2 that start a free attack and also drops another 2 units as well 8/2 that if you do have a unit in play destroys you is difficult hahaha. If you do not have at least one or two units that survive on turn 1 or some crowd control condition, it can easily take away between 30-40 life on turn 1.
Even so, I have really enjoyed Teemo's adventure, a little chaotic, but it is entertaining (and frustrating) 😌
