mtg question: What is in a faction pack?

Scars of Mirrodin is divided into two factions: Mirrian and Phyrexian. Each faction has its own symbol. Each card, except of basic lands and planeswalkers in the Scars of Mirrodin block (Scars of Mirrodin, Mirrodin Besieged, "Action" >> either called Mirrodin Pure or New Phyrexian) has a watermark in the text box area. This watermark tells you if a card is in Mirrian or PHyrexian faction.

Mirrodin of Besieged Faction Pack:

You get 1 basic land, 10 common, 3 uncommon and 1 rare from the chosen faction. In the case of foil, you get 9 common instead and the foil is random. So it is possible to pull a Mirrian foil rare in a Phyrexian faction pack.

Mirrodin of Besieged regular pack:

You get 1 basic land, 5 Mirrian common, 5 Phyrexian common, 3 random uncommon and 1 random rare. In the case of foil, you "lose" a random common.
