* Level Up! allows you to Special Summon a monster from your hand or deck with a level higher than the one you control. However, Armed Dragon LV5 cannot be Special Summoned from the deck, only from the hand.
* Tribute Summoning involves sending monsters from your hand or field to the Graveyard to Special Summon a monster. However, Armed Dragon LV5 doesn't have a Tribute Summon requirement.
* Special Summoning from the Deck Armed Dragon LV5 has a specific condition for Special Summoning from the deck. You need to control a "Armed Dragon" monster with a lower level to Special Summon it.
In summary, you cannot Special Summon Armed Dragon LV5 directly from your deck using Level Up! and Tribute Summoning. You need to either have Armed Dragon LV5 in your hand or control another Armed Dragon monster with a lower level to Special Summon it.
