The major differences being you play with 30 life instead of 20, legends aka heroes can't be targeted by spells aka abilities, you can have 5 copies of a card in your deck instead of 4, and finally there's no lands instead you can place a card from your hand face down once per turn as a land which provides a resource of the faction it belongs to when tapped.
The legend rule for heroes is a bit different also; there can only be one hero unit in play under your control at a time and if a hero unit you control is defeated you lose 10 life.

[Rules and Information]
structure = artifacts creatures that can't attack but can block, they can only be damaged by units with ground weapons.
upgrades = enchantments, no way to destroy them in game.
ground unit = creatures
arial unit = flying creatures
heroic unit = there can only be one hero unit in play under your control at a time, if a hero you control is defeated you lose 10 life.
defense = toughness
attack = attack power
cloak = shroud + unblockable as long as your opponent doesn't control a detector.
shield = absorb, prevents damage.
splash = Abilities from your hand affect adjacent unit to the target.
Damage caused wether through combat or an activated ability also affects adjacent units to the target for half the damage dealt rounded down.
ability = instant.
activated ability on a unit = instant speed.
Upgrades of the same name don't stack.
Players have 30 life points.
unit =/= hero.
5 copies of a card per deck.
When a card calls for a biological target it can also target a psyonic unit instead because psyonic units are all biological but when a card calls for a psyonic target a biological unit can not be selected instead.
"biological = psyonic
psyonic =/= bilogical"
