I need ideas for building an Aragorn, King of Gondor deck

I have an idea to take advantage of the effect of Aragorn, King of Gondor and creatures with strong effects, either when attacking or with ETB, but I'm new in this tcg and don't know of any powerful cards that could help in the deck. I already have some ideas for creatures with ETB to blink Aragorn's effect or enchantments to become the monarch. Could you help me with ideas for creatures and other cards for this purpose? Low mana costs are also appreciated.
