Each Evolution Creature features a rotating star-like symbol next to the 進化クリーチャー (Evolution Creature) written on their card frame as well as the symbol appearing in the creature's artwork.
It is strongly recommended to put an evolution creature on top of a creature with the same civilization as the evolution creature, and it is also recommended to put an evolution creature on top of a creature that is weaker than the evolution creature itself. This includes effect, power and cost. For example, if you want to summon Bell the Elemental, you may put it on top of Nam=Daeddo, Bronze Style because it is a weaker creature, but don't put it on top of Saurupio, Ancient King as it is a much stronger creature and doing so only causes waste.
A vortex evolution is a special type of creature. It is similar to an evolution creature but unlike an evolution creature, it requires 2 creatures to evolve from. The card text states which type of creature (like race or civilization) the vortex evolution requires to evolve from. You need to have at least one creature of both those qualities in the battle zone to summon a vortex evolution creature. Once you have the required creatures, put one of those creatures on top of the other and while summoning the vortex evolution, put it on top of that stack.
Remember that if the vortex evolution creature is from 2 different civilizations, you still need to tap at least one mana of the same civilization as each of those civilizations. For example, while summoning Aura Pegasus, Avatar of Life, you need to tap at least one Nature and one Light mana to summon it.

Summoning an evolution creature works just like summoning a regular creature except you can only summon an evolution creature when you have the correct type of creature (whether it needs a specific race, civilization, or ability) already in the battle zone. The evolution creature tells you what the creature it evolves from needs to have.
Once you summon an evolution creature, place it on top of the creature it "evolves" from. Leave that creature underneath the evolution creature, but ignore it any effects, power or other attributes it might have. Only the evolution creature's name, abilities, civilization, and power matter. Evolution creatures don't get summoning sickness even if the creature they evolved from had summoning sickness, so you can attack immediately after you put them into the battle zone. There's no limit to the number of evolution creatures you can put on top of each other.
An evolution creature is put into the battle zone in the same tap position as the creature it is put on. If it is put on a creature that is untapped, it is untapped. If it is put on a tapped creature, it enters the battle zone tapped.
If an evolution creature is moved from the battle zone to anywhere else, then the whole pile moves, not just the evolution creature on top. As long as the evolution creature is in play, it and the card it evolved from count as only one card. As soon as the pile ends up somewhere other than the battle zone, they are separate cards again. So if a card effect tells you put your evolution creature into the mana zone, you get that many separate cards in your mana zone.
However, when a card underneath the evolution creature is removed, the evolution creature itself remains in the battle zone. If only the top card of the evolution creature is removed (by an ability such as Dias Zeta, the Temporal Suppressor or Royal Durian), the player controlling the evolution creature can only have the same amount of creatures under it equal to the number of creatures required for the evolution, and the rest into your graveyard. For example, if the top card of Zeek Cavalie, Lord of Dragon Spirits is removed, one of the creatures under it stay in the battle zone and the rest goes into your graveyard. Super Infinite Evolution is exempt from this rule since it has no designated number of evolution bait. Evolution creatures and linked Gods can be counted as 1 creature. Also, removing the top card now counts as targeting the creature itself, and will trigger effects that involve the creature being targeted/leaving the field etc.
■ Saver: Evolution Creature(When one of your Evolution Creatures would be destroyed, you may destroy this creature instead.)
They are 2 un-keyworded forms of the Evolution ability; Blocker evolution (a creature that can be evolved on a creature that has Blocker), and Dual evolution (a creature that can evolve on a choice of 2 difference races).
