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) 3 (Players dealt combat damage by this creature also get three

The player who proliferates chooses which player that is. See rule 810, “Two-Headed Giant Variant.” (CR 701.34). (Choose any number of permanents and/or players, then give each another
