BUG - Rat King disappear ability not triggering
When playing Rat King in Arena (standard or standard ranked) on mobile, the disappear ability is not spawning 1/1 creatures or adding +1/+1 to Rat King when other permanents I control leave the battlefield. For example, when I play Airbender Ascension and use it to exile a creature and return it to the battlefield, it does not trigger Rat King’s disappear ability.

End step blinking does not suffice to fulfil Rat Ring, Verminster's disappear ability. Due to the intervening-if clause, a permanent must have left under your control before the end step begins.
603.4. A triggered ability may read “When/Whenever/At [trigger event], if [condition], [effect].” When
the trigger event occurs, the ability checks whether the stated condition is true. The ability triggers
only if it is; otherwise it does nothing. If the ability triggers, it checks the stated condition again as it
resolves. If the condition isn’t true at that time, the ability is removed from the stack and does
nothing. Note that this mirrors the check for legal targets. This rule is referred to as the “intervening
‘if’ clause” rule. (The word “if” has only its normal English meaning anywhere else in the text of a
card; this rule only applies to an “if” that immediately follows a trigger condition.)
