False Gods have triple marks. There is no way to get them.
Unless you win an Elements tournament. After you win an optional prize (instead of a nymph) is a mark card. These act like normal pillars but if your mark is the same element as the card it will stack. But this is not nearly as beneficial as a 2x mark by default would be since you do have to draw the card.
As to the nymphs, the only way you can get them is through the oracle or winning a tournament. Or use nymph's tears (a water card) on one of your pillars which will create the corresponding nymph.
