Block says: "Next time target champion within 7 spaces makes a close-combat attack against this unit, that attack automatically misses. This effect is hidden until triggered. This effect does not trigger if this unit is Paralyzed or Stunned. (You may target this unit to Block the next close-combat attack from any champion.)" Next time TARGET champion - if this is accurate, that means block will only block a champion that has been targeted - or it is not working. So, if a champ blocks, the next attacker will be blocked, rather than the selected. But it makes less sense with the range in there too. If it should be: "Next time a champion makes a close-combat attack..." Unless there is a way to make a close-combat attack from a range. Maybe Swoop? Either way, this should be worded better.
Block has two options. When you activate the ability, if you target your own champion, it will just block the next incoming melee attack. Let's say, however, that there are three enemy melee attackers that are close to your unit, one with 2 DMG, one with 5 DMG, and one with 17 DMG. When you activate block, if you click onto the 17 DMG melee attacker, then the next time that unit attacks you, it will be blocked, so this means that if the 2 DMG and 5 DMG attack first, those attacks will not be blocked.
