HasteHaste is a static ability.
If a creature has haste, it can attack even if it hasn’t been controlled by its controller continuously since their most recent turn began. (See rule 302.6.)
If a creature has haste, its controller can activate its activated abilities whose cost includes the tap symbol or the untap symbol even if that creature hasn’t been controlled by that player continuously since their most recent turn began. (See rule 302.6.)
Multiple instances of haste on the same creature are redundant. (CR 702.10)
Whenever Calamity attacks while saddled, choose a nonlegendary creature that saddled it this turn and
createTo create one or more tokens with certain characteristics, put the specified number of tokens with the specified characteristics onto the battlefield.
If a replacement effect applies to a token being created, that effect applies before considering any continuous effects that will modify the characteristics of that token. If a replacement effect applies to a token entering the battlefield, that effect applies after considering any continuous effects that will modify the characteristics of that token.
Previously, an effect that created tokens instructed a player to “put [those tokens] onto the battlefield.” Cards that were printed with that text have received errata in the Oracle card reference so they now “create” those tokens. (CR 701.7) a tapped and attacking token that's a copy of it.
SacrificeTo sacrifice a permanent, its controller moves it from the battlefield directly to its owner’s graveyard. A player can’t sacrifice something that isn’t a permanent, or something that’s a permanent they don’t control. Sacrificing a permanent doesn’t destroy it, so regeneration or other effects that replace destruction can’t affect this action. (CR 701.21) that token at the beginning of the next end step. Repeat this process once.
SaddleSaddle is an activated ability. “Saddle N” means “Tap any number of other untapped creatures you control with total power N or greater: This permanent becomes saddled until end of turn. Activate only as a sorcery.”
Saddled is a designation that has no rules meaning other than to act as a marker that spells and abilities can identify. Only permanents can be or become saddled. Once a permanent has become saddled, it stays saddled until the end of the turn or it leaves the battlefield. Being saddled is not a part of the permanent’s copiable values.
A creature “saddles” a permanent as it’s tapped to pay the cost to activate a permanent’s saddle ability. (CR 702.171) 1
