because he was supposedly going to use the Shrine of Mercy to summon Angels on day 1 and, to speed things up, attacked 20-49 Elves on the grass – a truly masterful play, nothing more to say.
The irony here is unclear.
1) Angels can be easily summoned on day 1.
2) There could have been 22 Elves without upgrades, and they can be defeated with a loss of 2-3 Marksmen, 5 Archers, and a Griffin.
Don't be afraid of Archers. 20 Elves are just 20 creatures of level 3.
