I tried to build angels in W1, as I had 17k gold and 115 experience, but I messed up the last chain, lacking 500 gold. Nevertheless, I took 2 conquests (125 and 6) as I had dwellings for pikemen, archers, swordsmen, and cavalry (I built the cavalry dwelling after taking the conquests). So, with 50 marksmen, 19 crusaders, and 2 champions, I started working. I saw all the beautiful treasures in the game, and after heading towards my opponent's town, I finally figured out how to get there. I decided to clear one treasure before going there, as it was almost on the road, but there were only 2 hives and a red orb guarded by many magic elementals, so I gave up on taking it. At level 135, I would have broken into this awesome treasure and taken the Horn of Heaven and 4 hives. But my opponent suicided in the top this day. Overall, it was a huge mistake to go for angels. I took too much risk, while if I had built cavalry, I would have taken conquests 122 and done everything faster, with a larger army and more safely. Also, 5 champions are approximately equal to 2 angels, so this pays off only if one is sure about having enough gold, an external market, or many good money-generating objects.
Thanks for playing.
