when a card says whenever you cast a spell that targets a creature, when summing it does that count as a spell
Only spells that have the word target in them count as targeting something.
The summoning of a creature does not count as targeting that creature.
Rule 114 deals with defining targeting.
114.1a (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=114.1a): An instant or sorcery spell is targeted if its spell ability identifies something it will affect by using the phrase "target [something]," where the "something" is a phrase that describes an object, player, or zone. The target(s) are chosen as the spell is cast; see rule 601.2c. (If an activated or triggered ability of an instant or sorcery uses the word target, that ability is targeted, but the spell is not.)
Example: A sorcery card has the ability "When you cycle this card, target creature gets -1/-1 until end of turn." This triggered ability is targeted, but that doesn't make the card it's on targeted.
114.1b (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=114.1b): Aura spells are always targeted. These are the only permanent spells with targets. An Aura's target is specified by its enchant keyword ability (see rule 702.5, "Enchant"). The target(s) are chosen as the spell is cast; see rule 601.2c. An Aura permanent doesn't target anything; only the spell is targeted. (An activated or triggered ability of an Aura permanent can also be targeted.)
114.1c (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=114.1c): An activated ability is targeted if it identifies something it will affect by using the phrase "target [something]," where the "something" is a phrase that describes an object, player, or zone. The target(s) are chosen as the ability is activated; see rule 602.2b.
114.1d (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=114.1d): A triggered ability is targeted if it identifies something it will affect by using the phrase "target [something]," where the "something" is a phrase that describes an object, player, or zone. The target(s) are chosen as the ability is put on the stack; see rule 603.3d.
114.1e (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=114.1e): Some keyword abilities, such as equip and provoke, represent targeted activated or triggered abilities. In those cases, the phrase "target [something]" appears in the rule for that keyword ability rather than in the ability itself. (The keyword's reminder text will often contain the word "target.") See rule 702, "Keyword Abilities."
