When going Silver Tree trade as Mongols, build military presence first so you don't lose your traders.

In Castle Age without Kurultai, there's no way the Mongol army ever holds a candle to the Ayyubid army. They have better units and better siege.

Mongol archers are just better in the feudal age than Ayyubid archers due to that extra range that the Khan's Hunter will give.

With incendiary arrows, elite archers are going to be on a tear against most of what Ayyubids have; only the camel lancers have a chance of surviving for a while longer.

I think tower rushing also isn't the most optimal here as the Mongols mainly for the reason that if the Ayyubids age up with the logistics wing and they get the free Dervishes with it, it is very very easy for them to just burn down the Outpost. Incredibly easy for them to just burn down the Outpost or they could also just go to another gold and if you spearman just rally after like villagers with Dervish healing support can just take any fight up against spears.
