FlyingFlying is an evasion ability.
A creature with flying can’t be blocked except by creatures with flying and/or reach. A creature with flying can block a creature with or without flying. (See rule 509, “Declare Blockers Step,” and rule 702.17, “Reach.”)
Multiple instances of flying on the same creature are redundant. (CR 702.9)
ToxicToxic is a static ability. It is written “toxic N,” where N is a number.
Some rules and effects refer to a creature’s “total toxic value.” A creature’s total toxic value is the sum of all N values of toxic abilities that creature has.
Combat damage dealt to a player by a creature with toxic causes that creature’s controller to give the player a number of poison counters equal to that creature’s total toxic value, in addition to the damage’s other results. See rule 120.3. (CR 702.164) Spores — At the beginning of your end step, if a permanent you controlled left the battlefield this turn, each opponent loses 3 life.
